Here is an example of a KAM headstamp I have not seen before. It is 41 dated and has a plain “St” headstamp instead of the typical “St+” I’ve seen on all other KAM production from 1941. This particular round shows some corrosion in the area where the lot # would normally be. I’ve looked at the round under a 16x glass with lots of light and it appears that there never was a lot# there. It is loaded with a natural wood (no dye) Platz Patronen 33 projectile. Anyone else out there have any like it to compare?
