Today I picked up three British artillery shell fuses at one of those flea markets I mention. I no nothing about fuses, so anything anyone can tell me on these would be welcome. I know that they ARE inert, as I can see a cavity in the base with a sharp firing pin at one end. I am interested in restoring these to original condition, should I do that or not?
The first one (below) is made by Vickers, Son and Maxim, it is marked marked: “V.S.M 80IVA 1/17 925D” on the inside base. It also has simple “H” on the very tip of the aluminium nosecone. It is graduated from 0-22, which I take it is time delay in seconds. It looks to be screwed into an adaptor (the part with remnants of orange paint).
The second one (below), is the same model as the first, but has no adaptor. It is marked “V.S.M. 80IVA 10/16 291C”. It also has the markings “VSM 80IVA 291C 10/16” round the edge of the base of the aluminium nose cone. There are no paint markings or visible paint traces.
The third one (below) has been fired as the threads are stripped. It is all aluminium, and the visible marking are: “80 III Co” and “50” over “44”, separated with a line. On the base, there is also a broad arrow and some numbers I cannot make out. This is also graduated from 0-22. It has the remains of a large blue “T” shape on one side (visible in photo).
Below are all three shown together:
