A Brief Introduction To Firearm Proof Marks

- I discuss the purpose of proving firearms and describe proof marks. I then show a variety of examples of different firearms and discuss what each mark means.
For a much more comprehensive look at firearm marks watch Forgotten Weapons' video:
• Introduction to Proof ...
For a good reference for proof marks from a lot of countries plus date codes look here:
shotguns.se/htm...
Reference Book Mentioned is:
The Standard Directory of Proof Marks by Gerhard Wirnsberger.
Pre 1954 proof marks were measured in fractions. 13 bore equals .709 in imperial when the decimal system came in after '54. The fraction 13/1 means the bore is .719. If they were stamped 12 then they would be .729 which is still used today. Of course in the UK they now use metric which equates to 18.5mm. It all stems back to a ball of lead that weighed a 12th of a pound would fit through the bore top to bottom then that barrel would be stamped 12. So a ball of lead that weighed a 13th of a pound that slid down the bore denoted that that barrel would be a 13 bore. Yes the diamond denotes which calibre of cartridge is used in the chamber.
excellent videos, many thanks for sharing and taking the time to make these. I like my late father am a english shotgun tragic. Cheers mate
Wow a pair of nitro proofed Damascus shotgun barrels. I never knew that was possible. Thanks!
Hello there, i got myself an German flobert parlor pistol yesterday, its a long version, it has a Crown over Crown over U stamp different Crowns, what can it be? Is it ok to shoot 22.short in it maybe ? I have had a few of the short floberts, and that was just 6mm floberts, but i have read about some of these can also use 22.short since not all of them are from 1890,s a local wepons dealer here told me thst it was kind of in rhe grey zone now selling these type of pistols, is it from before 1890, and it can be proved, its no problem, then its just 18 years old and then you can own it, but if the gun is newer and just looking old, then you have to have a licence, hope for answer :) Best regards from Norway
I bought an old double barrel hammer gun with a 2 barrel case and a set of 12ga, barrels , the owner said his father had bought it home from ww2 , it also had a set of rifle barrels but some how they were lost. , i cant find much info on the gun it has I Hollis on the very large frame , I would like the have a set-of rifle barrels made for if i knew the-cal ,
Isaac Hollis was a gun maker in Birmingham at the end of the 19th century who made sturdy but basic guns many of which were exported to India, Africa and Australia. I have seen many old Hollis guns at the range here in Australia. In good condition your gun would only be worth a few hundred dollars. I doubt very much whether there was ever a set of rifle barrels for it. There may have been a second longer or shorter set of shotgun barrels but even that is unlikely with a Hollis as it is mainly seen with higher grade guns. The other possibility is that the case is not original with the gun. Does it have a genuine Hollis trade label on it?
As I said your gun is only worth a few hundred dollars. To make a set of rifle barrels would take a gunsmith who is highly skilled in old fashioned gun making techniques and would likely cost $10000 or more. Clearly not an option.
Have a question about a rifle you did a vid on about a year ago .. Springfield 187j .. looking for a tip \fix . The tube mag is not feeding after the first shot. I would appreciate any suggestions or ideas on why and or how to fix . Thanks for any n all help
I haven't done a video about that rifle. We are not allowed semi-autos. I did however do one on replacing tube magazine springs: th-cam.com/video/ye5-2qsPoj4/w-d-xo.html
In any tube fed rifle that isn't feeding this is a good start. If it is still not feeding you have to look at the lifter mechanism. A bit harder in a semi auto as everything happens very quickly. The type of jam may give an indication of what is going wrong. May be worth getting someone to film with a good camera and lighting then look at footage in slow motion which may show what is going wrong.
Hopefully you are still answering questions. I have a Neumann Bros 12 Ga. Hammer gun . It had the scroll-styled EL on the flats. Also an either ELG or FLG (hard to read) in an egg shape with a crown. It says “Damascus Finish” on the spine. I believe that it needs black powder loads, but I’ll wondering if any of those marks are clues? It’s hard to see the ‘perin’ I think I heard you say. Hard to see with the lighting in your video.
Hi Sandy
Your gun was made in Liege Belgium by Neumann Brothers. It is likely a trade grade gun as they were exported in large numbers to both the UK and North America. It has Damascus twist barrels and definitely should not be fired with modern cartridges. If in solid condition you could load cartridges with 3f black powder. I would recommend no more than 1oz shot. First you must work out whether it has 2 1/2 or 2 3/4” chambers. You can do this using a small ruler which you can use to feel the ridge at the front of the chamber. If it is 2 1/2” you can load cartridges by cutting the crimped part off fired cases then after loading them use a card and roll crimp. Do not use plastic wads. You need to get some felt wads.
@@456eec : Wow! That’s way more assistance than expected! Thanks so much! When I hold the barrel up to a light, (breech at face) I can see the necking down location. It appears to be close to 3”, so I’d say, 2 3/4” shells, but I’ll use a ruler as you say to confirm. Wish I could send you photos. Stock has dents and some indent lines. I’m musing about stripping the stock, steaming out the lines and dents and re finishing it. I know not much value there to warrant a complete restore. Also, one firing pin is broken and missing the bead site. Any place to shop for parts or have a friend make them on a lathe?
Brownells should have a sight bead. The firing pin will need to be made most likely. I have a vid on doing that.
I forgot to say you can get felt wads at Track if the Wolf. The correct size is 13ga as 12ga are only used in muzzle loaders.
@@456eec …at track if the wolf… I don’t follow you on that… So I should buy 13 ga. Wads, not 12 ga?
