Forgive me if this is a really stupid question.
I recently bought a couple of British WW1 fuses. One says 85-1 one it, so I assume it's a number 85 timed/percussion fuse. The other is similar, possibly a number 80, based on a faint number I can see on the base (after the lowest part has been unscrewed).
I realise, of course, that neither of these fuses is attached to the shell, the business end of the apparatus, but is it possible that either is still "live" in the sense that the detonator could still be intact?
If so, how much of a problem is this, and is there anything I need to do about it?
