2 sizes of German dust fuzes of WW2 for projectiles. Spinning the dust in side created enough electric current to fire the cap. Anyone care to identify the shells which they went to ?
Dam, that is cleaver thinking! Totally have never heard of them before, too cool! No clue on what they went to.
The smaller one on the left looks a little to me like what would be on the Czech 4,7cm HE type round, many of which the Germans utilized, a good example would be on the Pzjg I…but thats just going from memory…of course I could cheat and look them up in my German Explosive Ordnance manual tonight ;-)
Unfortunately that won’t do you any good.
