Fantastic inside ! The hidden double ranges were a nice bonus. I found two possible dates for it online - 1930 and 1952, the style of it looks more like 1952 to me though. The Science museum has a similar one, not identical, and that is quoted as 1952. Another image I found for this exact model shows one terminal has an insulator and the other does not, just like yours. I looked up that Ayrton-Perry non inductive winding method - hadn't met this before.
Wow, its absolutely beautiful inside. I bet it has that nice smell of old electronics. They definitely don't make them like that any more. How much did you pay for it.
Extremely weird to see a couple of vishay foils? as replacements, along with an absolutely bog standard metal foil 1/4w, which I highly doubt meets the power rating it was initially specced for
I've used the Vishay bulk foil resistors in test loads, they are very stable, available in fairly precise values, and are non-inductive. They are not cheap though!

Yes it feels like it should be in a museum. The 50ties sound about right, about 70 years old, still going strong
Fine art indeed!

I did not notice any particular smell, but it is a work of art just visually. Paid about £40
At 9:49 the cylindrical resistors look like high voltage insulators.

yes, I definitely do not plan to run significant power through these. just using it as a resistor reference
