Hallo,
I don't think that crimpers are a current issue item with the military. As far as I know, none of the big producers manufactures "normal blasting caps" any more, since quite a few years. In civilian blasting they are not used any more since decades. The only use that I know of, where they still may be used, is "Avalanche Blasting" in the high mountain regions. My foto shows from left to right:
1.) A civilian crimperr with a stamped in logo of a sixsided prism, inside which R S Co. with a circle above the S and a picture-logo. I have not found any info about this company up till now.
2.) This is a so called model "Pionier"(Engineer) crimper used by the West-German army starting in the 50s. It is still sometimes offered from civilian blasting supply companies for around a 100 $
3.) This is the old style crimper of the East-German army, also from around the 50s.
4.) This is the new-style East-German crimper, which was used up till the end of the East-German army.
The last 3 crimpers, also historic items, are new and have never been used. These are quite expensive precision tools. The East-German factory issued their crimpers with a piece of timefuse onto which 2 dummy caps were crimped, as wittnes to the full function of the crimper and to show the type of crimp.
There seem to be very few people into collecting crimpers. Before I had quite a few, but sold off the last ones lying around, just a short while ago, for very small $.
