@@Backyard.Ballistics Don't get me wrong, we also preserve firearms with historical value. But in this case a sub-machine gun is classified as a class A weapon, so it's impossible for a civilian to own it, unless it's a deactivated weapon. In theory our law "may" allow collectors and private museums to have a functional machine gun. For that one needs a special license granted on a case by case basis by the national director of police. To my knowledge it´s always been denied to anyone asking for it. Thanks for doing this videos, I just wish you had more views, because you really deserve!
Pro tip to remove rust but keep your finish: Galvanic rust removal. Dissolve Sodium Carbonate in (preferrably warm) water, place an electrode in it and connect your part to negative. Apply 6-12V (6 works best for me) and let it do its magic for a few hours. Afterwards a regular brush will be able to remove whats left of the rust, leaving your with nothing but steel. Bluing will not be harmed at all. I have used this method many, many times. The result looks much better then it does after all your brushing, with probably 1% of the effort.
My revolver with rust doesn't have bluing, but I think it's some cover, this method won't remove the cover right? I got most of the rust off with oil, but there's some flaky parts on it.
@@urboyseth5922 I have seen some paints that where partly "lifted off" the material, in areas where it was cracked already. I think what happens is that bubbled form underneath the already lose paint that lift of the paint in this areas. Far less then any wire brush or steel wool would do though. With nitrited and phosphated finished I have no experiece, as these are really rare her ein europe. By my limited understanding of chemistry it should not harm it though.
Extra pro-tip instead of removing the rust. Convert it by boiling the parts in water then card off with OOOO steel wool or a super fine wire wheel (should be able to touch it while spinning) . It will convert it back into the original bluing and you end up with even less work.
@@d3faulted2 impossible. This concept of "converting" rust is a myth.. you can stoo the oxidation by revoming as much oxide from the rusted surface as possible but you will never convert anything back. Boiling in Water will not do much other then losening up expanded oxide.
@@just1ofgod well you're acting like firing a gun damages it. Plus there were millions of sten guns made, most of the surviving examples are in museums already. Honestly a private owned gun being shot and maintained regularly is a much better example for the younger generations than one in a glass display case gathering dust while all it's springs lose tension and become fragile
@@benb5308 most surviving ww2 semi/full auto guns I have worked on are shot out so yeah firing them does indeed degrade the components most standard high pressure rifle barrels have a prime life span of about 10000 rounds or so (depending on brand and quality) all of the main parts on a firearm are wear components.
@@just1ofgod that's if they're not taking care of, which granted back in the day a lot of people didn't do because they were cheap surplus, most of the damage on world war II guns happen in world war II when they were getting sand and grit in all the components and not getting cleaned regularly, but if people are cleaning and oiling regularly and not shooting them every single day they'll definitely be preserved better by being fired. And that 10,000 round estimate definitely not true for the lifespan of a firearm, most firearms break in period is the first 500 to 1,000 rounds, so unless it's a particularly fragile piece the gun should last way longer than 10,000 rounds if properly maintained. But honestly what does it matter if the firearm functions if it's going to a museum, it'll likely never be held, definitely will never be fired, they might as well just an empty shell and remove all the internals because it's just a glorified paperweight once a museum has its hands on it
There was a superficial layer with a very homogeneus color. It was definitely not paint though, it scraped away and crumbled way too easy. It had a powdery consistency
"I then proceeded to gently tap with a rubber mallet." Proceeds to beat it like it owes him money. Hey it worked. I am so glad the police called you. You knew how to first and foremost make sure the guns were safe. Then you were able to clean and lube it, stopping any damage from getting worse. Great that this bit of history will be preserved and put on display for the community to enjoy.
@@148crusader true and these are super easy to make. Some of the guns I manufacture are actually harder to make hahah but I want a true British made STEN.
Stems were made in all kinds of shops and meant to be quick and easy to manufacture for the the war effort when money was tight and men were fighting.. Great video.
I would love to see the reaction on the inventors of the sten if they found out people were 'preserving' a 'piece of history'... Stens were designed to be throwaway and disposable cheap crap, before throwaway disposable cheap crap was a thing!
For removing rust, I recommend evapo rust, which is, like its marketing claims, super safe. It does not harm the skin nor does it smell bad. Also, if you know how to blue metal, don't worry about removing the original bluing if you plan on re bluing the gun anyways. If you don't want to remove the blue, what you did is fine. I am a gunsmith from Texas and have restored a few firearms so far like a Swiss K11, a Calvary Carbine Carcano, a Ruger 10/22, Century Arms Sporterized L1A1, and fixed a Winchester 1897 that was not feeding right. I have done a lot of bluing, wood work, fabricating parts on a lathe and mill, and even jeweled a bolt from a friend's hunting rifle and I got to say, gunsmithing is an absolute joy of mine.
The firearm itself might be structurally sound, but is the rough surface left by the corrosion not going to accelerate wear between sliding surfaces, say the bolt and the receiver? I know you aren't a professional restorer, but would that be of any concern to one, or is the material already too badly damaged by that point for this to become a concern?
So in this specific case the firearm has undergone uniform corrosion and is almost entirely orange. This is actually a good thing which negates some excessive pitting, making the firearm potentially safe to shoot. In terms of safety and use, the sliding parts would probably be fine as long as the initial rust is mostly removed. However, the barrel and chamber are an issue. The higher tolerances required by most machine guns are negligible to think about for most of this firearm (as it is a simple tube gun) but the biggest issue I can think of is corrosion within the chamber. This corrosion can leave microscopic pits which can more easily grip a cartridge that is being forcefully pulled back by its rim. The rim and can ripped off and the case left behind in the chamber. But yeah it terms of corrosion within the tube there is most likely not a huge issue with exacerbated wear as the tolerances are low and the gun isn't being run dry. Also even if rust was still in the action rust is much less hard than steel and won't hurt the steel too much. Sources; I'm a corrosion engineering major
There is more than enough contact to resist wear. Pits will be spanned for the most part; if you are concerned about roughness. Besides, they are not going to shoot it very much.
It won't be a problem, there is very little sliding friction in this design (little force pushing the sliding surfaces one against the other), as is the case for most gun designs, woth some notable exceptions.

You are fortunate to have police that were kind enough to restore is iconic WWII relic. Our police force would have this destroyed once it was purged from impound. I know because I worked for a municipality who shall remain un-named that brought confiscated weapons to our shop to be cut up. Most of them were cheap junk but every now and then there would be some that you really wish you didn't have to destroy. 1911's, SKS, Mosin-Nagant, Mini-14's, AKs, and AR's and a few nice revolvers and shotguns.
Other than the red paint this seems like one of the better examples of survived weapons you have received to restore. Considering the quality of original manufacture standards this seems well preserved. Je ne sais quoi?
If you were in the US, I would love to see you try to clean and fix pawn shop guns. Because quite a bit of them just simply can't do just that let alone research the gun (from my experience).
@@NigelThornbery I know, but they should need to learn at least the basic name and the MSRP as well putting the condition of the said firearm into the equation.

I thought this was that other Italian channel by the gunsmith that restores guns like this He's done very similar work with a 9x21mm Uzi and an Italian pistol
Thank you for another fascinating and highly informative video -it always makes me happy to see that you have uploaded a new video, and this was no exception. Please keep up your excellent work, and are there any new developments regarding the unfortunate Serbu RN50 detonation?
Haven't heard anything else, but faulty ammunition (wrong powder type/load) seems the only cause of failure. And a simple cap redesign could make the gun failsafe
@@Backyard.Ballistics Thanks for your reply 🙂 To be honest, I had always assumed that the RN50 already was as failsafe as any firearm could really be, mainly because of its' simplicity and lack of moving parts to break. But as poor Scott unfortunately found out, if the cartridge is so dangerously overpressure as to detonate an RN50 then there really isn't much that anybody can do to safeguard against the irresponsibilty of negligent/dangerously-ignorant reloaders trying to make an easy buck, other than to do your own reloading and to take full responsibility for your own work. I sincerely hope that Mark Serbu's (slightly eccentric, but 100% unique...) business doesn't suffer unfairly as a result of this unfortunate incident because I admire his engineering, his presentation of information to his viewers in a way we can all understand, and his determination to do his own thing in his own way, and I also hope that people respect the power of .50BMG a little more than they did before Scott's accident.
I own a M3 Grease gun so for me there’s no comparison the Grease gun is better. Just better made, more reliable and shoots a better round 45 acp over 9mm. This also reflects in the price. A WW2 Grease gun can cost $30K to $35K. Sten’s are only $7K to $10K.
to all the people here claiming this and his other restorations are fake (probably for the attention they are already deprived of), if you know so much (you do not) then become a gun restorationist instead of bitching about a video you likely didn’t even watch. great video
Honestly I think that cold blue makes a good finish for a display piece if they end up keeping it that way. Pretty accurate depiction of what a well used smg would've liked like back in the day.
I get that Europe has been a war zone forever but I’m always amazed with how casual it is to find WW1 and WW2 relics over there. I know plenty of gun nerds here in the states who would kill for an authentic WW2 Thomspon, Mosin or K98 but people in Europe tend to find them under their homes. Tldr; we’re jealous :(
You're so fortunate to have this opportunity. Recently near me in the US a gentleman found several Thompsons buried in a crate out in the mountains. The gentleman attempted to find NFA paperwork for the weapons, and was unable to do such. I believe they were model 28s. Tragically, they had never been registered. Thusly, the guns were stripped and according to the law, the receivers were cut into 3 pieces with a blowtorch. It's tragic because many guns like this would be excellent examples of prohibition/great depression/wwi/wwii/Korean war/Vietnam War history in the US. But because of our stupid gun laws, we are forced to irreparably damage the weapons. We also are not allowed to register any new machine guns after 1986.
Land of pay your taxes or we'll take all your shit,which is both ironic and sickening at the same time. Seriously though even the bad bad uk didn't rip off said land so badly lol honestly it sucks that it didn't remain as free as those treasonous english rebels had intended
I like the idea of "conservative restoration". You bring the gun back to working condition, but you don't remove its history. I can feel your strong sense of history. Patina is more than just dirt and signs of use. Patina is history.
I’d hold onto that and the ammo instead of turning it over to a museum. Trust me with how things are going in Europe you are gonna need it in the near future.
@@MultiRokusho Who am I to say? I don't claim to predict the future and tell people to "trust me" about a topic I'm not knowledgeable enough to discuss. Who are you, a geopolitical expert who's privy to very sensitive information?
As a gun restorer you must have missed the video,s of the American gun restorer Mark Novak. In his tutorials from his channel " The Anvile" he could have told you that slight surface rust is a protecting layer on metal wich all restorers go wrong by scraping or scratching it off, damaging the surface of the object. He just cooks them in a soapy water bath over 100 dgr C. turning the brown rust into the black protecting patina , with saving all old blueing on the gun.
If you were, say, an eccentric in Canada with an idea for a really different kind of firearm action attempting to answer the rapid-fire question (effective burst-fire concentration,) who would you approach with the concept to get things moving in a legal fashion?
look up the Canadian legal definition of semi automatic and you'll find your answer. Short answer: Our definition is much tighter than the American one, meaning things like bumpstocks, binary triggers, Forced reset triggers etc are automatically prohibited by default.
About 25 years (we were teenagers back then) ago we have found the same one. It was hidden about 50 cm underground. Gun was in a great condition. Soldier used some kind of material covered with grease or oil (you could see black marks). We decided to show it to our history teacher :). She took it to the museum or something like that. So many years and I can't believe I was so stupid back then :D.
Your knowledge on these guns to take them apart and put them back together is amazing. Do you look up maintenance guides on them before tear down or just go in blind?
Steel wool does work as a rust remover with lubrication, however you may want to try using a copper brush and oil instead if you deal with a gun in the future where you want to preserve as much original finish as possible. 12 or 10 ga bore brushes work well for this, and as a softer metal you don’t run the risk of doing any damage to the steel surface. It’s a safer way to remove surface rust on nicely blued guns for this reason, since it will not harm the surrounding good bluing.

police in most ocuntries seize weapons, regardless of historical value
Normally firearms of artistical or historical value are preserved here
@@Backyard.Ballistics Don't get me wrong, we also preserve firearms with historical value. But in this case a sub-machine gun is classified as a class A weapon, so it's impossible for a civilian to own it, unless it's a deactivated weapon. In theory our law "may" allow collectors and private museums to have a functional machine gun. For that one needs a special license granted on a case by case basis by the national director of police. To my knowledge it´s always been denied to anyone asking for it. Thanks for doing this videos, I just wish you had more views, because you really deserve!
@@kevinmorrice Seize them and put them through a shredder, regardless of value. At least here in Denmark
Thats where my favorite restoration channel has started
Pro tip to remove rust but keep your finish: Galvanic rust removal. Dissolve Sodium Carbonate in (preferrably warm) water, place an electrode in it and connect your part to negative. Apply 6-12V (6 works best for me) and let it do its magic for a few hours.
Afterwards a regular brush will be able to remove whats left of the rust, leaving your with nothing but steel. Bluing will not be harmed at all. I have used this method many, many times. The result looks much better then it does after all your brushing, with probably 1% of the effort.
My revolver with rust doesn't have bluing, but I think it's some cover, this method won't remove the cover right? I got most of the rust off with oil, but there's some flaky parts on it.
@@urboyseth5922 I have seen some paints that where partly "lifted off" the material, in areas where it was cracked already. I think what happens is that bubbled form underneath the already lose paint that lift of the paint in this areas. Far less then any wire brush or steel wool would do though.
With nitrited and phosphated finished I have no experiece, as these are really rare her ein europe. By my limited understanding of chemistry it should not harm it though.
Extra pro-tip instead of removing the rust. Convert it by boiling the parts in water then card off with OOOO steel wool or a super fine wire wheel (should be able to touch it while spinning) . It will convert it back into the original bluing and you end up with even less work.
@@d3faulted2 impossible. This concept of "converting" rust is a myth.. you can stoo the oxidation by revoming as much oxide from the rusted surface as possible but you will never convert anything back.
Boiling in Water will not do much other then losening up expanded oxide.
I just love British war era guns, they are so simple that even after couple of decades rusting they are still functional
Very cool as a gunsmith I love seeing pieces of history like this brought back to life.
Too bad it's being sent to a museum, to never be fired or probably even held again
@@benb5308 something to be said for historical pieces being preserved for future generations though even if it's just to look at.
@@just1ofgod well you're acting like firing a gun damages it. Plus there were millions of sten guns made, most of the surviving examples are in museums already. Honestly a private owned gun being shot and maintained regularly is a much better example for the younger generations than one in a glass display case gathering dust while all it's springs lose tension and become fragile
@@benb5308 most surviving ww2 semi/full auto guns I have worked on are shot out so yeah firing them does indeed degrade the components most standard high pressure rifle barrels have a prime life span of about 10000 rounds or so (depending on brand and quality) all of the main parts on a firearm are wear components.
@@just1ofgod that's if they're not taking care of, which granted back in the day a lot of people didn't do because they were cheap surplus, most of the damage on world war II guns happen in world war II when they were getting sand and grit in all the components and not getting cleaned regularly, but if people are cleaning and oiling regularly and not shooting them every single day they'll definitely be preserved better by being fired. And that 10,000 round estimate definitely not true for the lifespan of a firearm, most firearms break in period is the first 500 to 1,000 rounds, so unless it's a particularly fragile piece the gun should last way longer than 10,000 rounds if properly maintained. But honestly what does it matter if the firearm functions if it's going to a museum, it'll likely never be held, definitely will never be fired, they might as well just an empty shell and remove all the internals because it's just a glorified paperweight once a museum has its hands on it
What a wonderful find. Maybe I'll check my basement for one ;-) Thanks for walking us through your conservation steps.
Let us know, did ya find anything nice 😂
Nice job, the sten gun is a beautiful piece of history
This is why I love your channel. Concise and to the point. Lots of info. Thanks, mate.
I always loved this submachine gun.
It's extremely beautiful.
Yup, THIS Is how you properly restore guns! Great work.
That rust was so thick, it looked like pink paint!
There was a superficial layer with a very homogeneus color. It was definitely not paint though, it scraped away and crumbled way too easy. It had a powdery consistency
"I then proceeded to gently tap with a rubber mallet."
Proceeds to beat it like it owes him money.
Hey it worked.
I am so glad the police called you.
You knew how to first and foremost make sure the guns were safe.
Then you were able to clean and lube it, stopping any damage from getting worse.
Great that this bit of history will be preserved and put on display for the community to enjoy.
Who knows how he does it?😮That's amazing, isn't it?👍
i love how he gives us as much information about this as possible like we're gonna restore a firearm
I mean, grandpas trunk still has stuff in it…
Glad to know it's going to a museum and not getting destroyed
Damn I wish I owned that thing. I’d love a beaten ass sten that still shoots and isn’t neutered. One of the coolest sub guns ever made.
The blueprints exist :)
@@148crusader true and these are super easy to make. Some of the guns I manufacture are actually harder to make hahah but I want a true British made STEN.
Stems were made in all kinds of shops and meant to be quick and easy to manufacture for the the war effort when money was tight and men were fighting.. Great video.
Thank you for saving that piece of history. 👍
My pleasure
I would love to see the reaction on the inventors of the sten if they found out people were 'preserving' a 'piece of history'...
Stens were designed to be throwaway and disposable cheap crap, before throwaway disposable cheap crap was a thing!
For removing rust, I recommend evapo rust, which is, like its marketing claims, super safe. It does not harm the skin nor does it smell bad. Also, if you know how to blue metal, don't worry about removing the original bluing if you plan on re bluing the gun anyways. If you don't want to remove the blue, what you did is fine. I am a gunsmith from Texas and have restored a few firearms so far like a Swiss K11, a Calvary Carbine Carcano, a Ruger 10/22, Century Arms Sporterized L1A1, and fixed a Winchester 1897 that was not feeding right. I have done a lot of bluing, wood work, fabricating parts on a lathe and mill, and even jeweled a bolt from a friend's hunting rifle and I got to say, gunsmithing is an absolute joy of mine.
Yup , I would've just chucked the whole thing in a bath of evaporust before even trying any disassembly.
What works best is just to boil the parts. Adopted this after seeing it on Mark Novaks channel
I appreciate your narration about your thought process. Made for a much more interesting video.
The firearm itself might be structurally sound, but is the rough surface left by the corrosion not going to accelerate wear between sliding surfaces, say the bolt and the receiver? I know you aren't a professional restorer, but would that be of any concern to one, or is the material already too badly damaged by that point for this to become a concern?
So in this specific case the firearm has undergone uniform corrosion and is almost entirely orange. This is actually a good thing which negates some excessive pitting, making the firearm potentially safe to shoot.
In terms of safety and use, the sliding parts would probably be fine as long as the initial rust is mostly removed. However, the barrel and chamber are an issue. The higher tolerances required by most machine guns are negligible to think about for most of this firearm (as it is a simple tube gun) but the biggest issue I can think of is corrosion within the chamber. This corrosion can leave microscopic pits which can more easily grip a cartridge that is being forcefully pulled back by its rim. The rim and can ripped off and the case left behind in the chamber.
But yeah it terms of corrosion within the tube there is most likely not a huge issue with exacerbated wear as the tolerances are low and the gun isn't being run dry. Also even if rust was still in the action rust is much less hard than steel and won't hurt the steel too much.
Sources; I'm a corrosion engineering major
Whoopsh!
There is more than enough contact to resist wear. Pits will be spanned for the most part; if you are concerned about roughness. Besides, they are not going to shoot it very much.
It won't be a problem, there is very little sliding friction in this design (little force pushing the sliding surfaces one against the other), as is the case for most gun designs, woth some notable exceptions.

Did you use paint thinner to remove the old paint residue?

The sten gun was actual genius. Simple. Easy to manufacture. Reliable. Easy to fix. Theres no finesse there, but it did what it was designed to do, at a low cost. It was an ak47 before there was an ak47.
Beautiful, meticulously precise and detailed narration combined with superb videography, lighting and editing make this video a joy to watch.
It comes as no surprise that the channel owner is an Expert Witness, any hearing he attends will be very well informed on the matter in which he presents. Subscribed.
If this piece was truly rusted ,then why does it release the clip and the bolt move freely ? Hhhmmmm,hhhhhhmmmmmm.
You are fortunate to have police that were kind enough to restore is iconic WWII relic. Our police force would have this destroyed once it was purged from impound. I know because I worked for a municipality who shall remain un-named that brought confiscated weapons to our shop to be cut up. Most of them were cheap junk but every now and then there would be some that you really wish you didn't have to destroy. 1911's, SKS, Mosin-Nagant, Mini-14's, AKs, and AR's and a few nice revolvers and shotguns.
It really looks more like someone painted it bright red, ive never seen rust that color.
Looks like its been deliberately 'rusted' with a chemical for the vid IMHO
You've never seen orange rust?
Hey Brother, I was surprised by and deeply appreciated the educational aspect you added to the video. Thank you for enlightening me. Very Cool!
As a corrosion engineering major I knew that the gun was salvageable BECAUSE it was so orange. Uniform corrosion >>>> pitting
orange rust is new rust and not old time rust...a lot of video such like this one show fake restauration
You said that you are not a profesional restaurador. But my friend, you are an amazing restorator.
A brass or stainless wire wheel would have saved you a ton of time. Awesome piece of history!
I quite agree on that
I can tell you are still good buds with your old job buddies in away
I'm still working with them😉
Other than the red paint this seems like one of the better examples of survived weapons you have received to restore. Considering the quality of original manufacture standards this seems well preserved. Je ne sais quoi?
If you were in the US, I would love to see you try to clean and fix pawn shop guns. Because quite a bit of them just simply can't do just that let alone research the gun (from my experience).
Because it’s a pawn shop. Key word pawn, not gun shop or gun store.
@@NigelThornbery I know, but they should need to learn at least the basic name and the MSRP as well putting the condition of the said firearm into the equation.
@@killertruth186 them not knowing what it is often works in your favor. It is old and has some rust get it out of my shop. If it is over priced you just walk away.
It’s surprisingly not in “horrible condition” it’s just rusty as all hell and is missing the wire stock, but other than that everything seems to be in working order…it just needs some loving!!
A good trick for stuck bolts and parts is to use a 50-50 mix of automatic transmission oil and acetone
I've heard about it, never tried it myself though, and didn't have any ATO at hand
Your explanation made me want to become a Science student, studing Engeering🙌🏽
Great variety on this awesome channel. I just joined your Patreon. Thanks for your fun & informative content here.
How’s your Light gas gun project going?
I was working on that when I got the call for the stens, and couldn't not make a video about them
I thought this was that other Italian channel by the gunsmith that restores guns like this
He's done very similar work with a 9x21mm Uzi and an Italian pistol
Wow, if those guns could talk. Very interesting, I enjoy these types of video. Thank you for telling us why you do it too.
Thank you for another fascinating and highly informative video -it always makes me happy to see that you have uploaded a new video, and this was no exception.
Please keep up your excellent work, and are there any new developments regarding the unfortunate Serbu RN50 detonation?
Haven't heard anything else, but faulty ammunition (wrong powder type/load) seems the only cause of failure.
And a simple cap redesign could make the gun failsafe
@@Backyard.Ballistics Thanks for your reply 🙂
To be honest, I had always assumed that the RN50 already was as failsafe as any firearm could really be, mainly because of its' simplicity and lack of moving parts to break.
But as poor Scott unfortunately found out, if the cartridge is so dangerously overpressure as to detonate an RN50 then there really isn't much that anybody can do to safeguard against the irresponsibilty of negligent/dangerously-ignorant reloaders trying to make an easy buck, other than to do your own reloading and to take full responsibility for your own work.
I sincerely hope that Mark Serbu's (slightly eccentric, but 100% unique...) business doesn't suffer unfairly as a result of this unfortunate incident because I admire his engineering, his presentation of information to his viewers in a way we can all understand, and his determination to do his own thing in his own way, and I also hope that people respect the power of .50BMG a little more than they did before Scott's accident.
this is it, this is the channel i needed that i didnt know i needed
Awesome refurb, would love to do a sten mk 2 or mk 4 kit build some day, thanks for the vid!
Which was the superior weapon and why, the Sten or the M3 "Grease Gun?"
I own a M3 Grease gun so for me there’s no comparison the Grease gun is better. Just better made, more reliable and shoots a better round 45 acp over 9mm. This also reflects in the price. A WW2 Grease gun can cost $30K to $35K. Sten’s are only $7K to $10K.
to all the people here claiming this and his other restorations are fake (probably for the attention they are already deprived of), if you know so much (you do not) then become a gun restorationist instead of bitching about a video you likely didn’t even watch. great video
Honestly I think that cold blue makes a good finish for a display piece if they end up keeping it that way. Pretty accurate depiction of what a well used smg would've liked like back in the day.
It’s amazing how red oxide primer makes things look rusty , making a restoration very easy
Thoroughly enjoyed this video! If that gun could talk!
If this will ever shoot again?... Noooo. absolutely not! I will discard of it for you, no worries!
I get that Europe has been a war zone forever but I’m always amazed with how casual it is to find WW1 and WW2 relics over there. I know plenty of gun nerds here in the states who would kill for an authentic WW2 Thomspon, Mosin or K98 but people in Europe tend to find them under their homes.
Tldr; we’re jealous :(
But...but...I want to be the guy the police call when they find WWII weaponry.
I'm not complaining, but they also call you in much less fun circumstances
You're so fortunate to have this opportunity. Recently near me in the US a gentleman found several Thompsons buried in a crate out in the mountains. The gentleman attempted to find NFA paperwork for the weapons, and was unable to do such. I believe they were model 28s. Tragically, they had never been registered. Thusly, the guns were stripped and according to the law, the receivers were cut into 3 pieces with a blowtorch.
It's tragic because many guns like this would be excellent examples of prohibition/great depression/wwi/wwii/Korean war/Vietnam War history in the US. But because of our stupid gun laws, we are forced to irreparably damage the weapons. We also are not allowed to register any new machine guns after 1986.
Why the hell didn’t you just keep them secret and not say anything? If you can’t find the paperwork, don’t say anything and keep them in a safe place
@@lilrobi45xxx42 if you are found out, you will face a $250,000 fine and 10 years in federal prison.
@@lasersharksushi1975 that’s if you get caught, you just have to be careful with them.
@@lilrobi45xxx42 you'll inevitably get caught. Having a rusty MG isn't worth losing all of your rights.

I laugh cause I'm in the "land of the free" where you can't even legally do this. More like land of illusion.
In the “land of the free” ATF would shoot your dog.
Land of pay your taxes or we'll take all your shit,which is both ironic and sickening at the same time. Seriously though even the bad bad uk didn't rip off said land so badly lol honestly it sucks that it didn't remain as free as those treasonous english rebels had intended
I like the idea of "conservative restoration". You bring the gun back to working condition, but you don't remove its history. I can feel your strong sense of history. Patina is more than just dirt and signs of use. Patina is history.
Imagine the police calling *you* when they find a gun
😂
Explaining each process is real detailed. Nice work
A lot of rusty guns have been "found" recently.
I wonder how many were found inside a bathtub with salt water in it.
This looks incredibly fake
Underrated channel. I very much enjoy the content.
I’d hold onto that and the ammo instead of turning it over to a museum. Trust me with how things are going in Europe you are gonna need it in the near future.
Why should we trust a random person on the Internet about Europe's future?
@@lptomtom do you think it’s gonna go swimmingly there?

@@tesstickle7267 Wow, another geopolitical expert! Now that's lucky, who would've thought they congregate in the comments of gun restoration videos?
As a gun restorer you must have missed the video,s of the American gun restorer Mark Novak.
In his tutorials from his channel " The Anvile" he could have told you that slight surface rust is a protecting layer on metal wich all restorers go wrong by scraping or scratching it off, damaging the surface of the object. He just cooks them in a soapy water bath over 100 dgr C. turning the brown rust into the black protecting patina , with saving all old blueing on the gun.
This looks like some one deliberately rusted it up. Weird
With paint...
It was very good. Good luck, dear friend 👏🏻👏🏻
Are you snitching? Or just finding if it works or not?
imma spend hours watching you restore old guns back to greatness now that I found your channel xD
The stens are the cheapest guns of ww2.
Nah. Some of those late-war German volksturm weapons are much cheaper and shittier.
Kroil, my friend. Angel piss. Freeing rusted metal parts since whenever it was invented.
If you were, say, an eccentric in Canada with an idea for a really different kind of firearm action attempting to answer the rapid-fire question (effective burst-fire concentration,) who would you approach with the concept to get things moving in a legal fashion?
look up the Canadian legal definition of semi automatic and you'll find your answer.
Short answer: Our definition is much tighter than the American one, meaning things like bumpstocks, binary triggers, Forced reset triggers etc are automatically prohibited by default.
I'm very glad that the police thought to give this weapon to you to restore for a museum instead of destroying it.
About 25 years (we were teenagers back then) ago we have found the same one. It was hidden about 50 cm underground. Gun was in a great condition. Soldier used some kind of material covered with grease or oil (you could see black marks). We decided to show it to our history teacher :). She took it to the museum or something like that. So many years and I can't believe I was so stupid back then :D.
Your knowledge on these guns to take them apart and put them back together is amazing. Do you look up maintenance guides on them before tear down or just go in blind?
This is my favorite video, the sten is my favorite gun along with the type100
I really love watching you work
Amazing Restoration
that is a verry strange red. is that all rust?
maybe the camera settings are off, but stil
Steel wool does work as a rust remover with lubrication, however you may want to try using a copper brush and oil instead if you deal with a gun in the future where you want to preserve as much original finish as possible. 12 or 10 ga bore brushes work well for this, and as a softer metal you don’t run the risk of doing any damage to the steel surface. It’s a safer way to remove surface rust on nicely blued guns for this reason, since it will not harm the surrounding good bluing.
Always love you videos. Great job and incredible craftsmanship
I like the narration part, lots of information.
