PYes , however , the ones used with those projectiles I’ve only seen with MG 204 cases aswell as 20x105/b ones marked L204 , Luftwaffe Versuch.
This one is just marked P M & seems to have a different primer too , or atleast something odd is going on with it.
I’m trying to make sure that this one isn’t used w/ other projectiles , as they did quite some other stuff in the mid 30s testing the S18-100 , 20x105 Solothurn “kurz”. & If I recall correctly , the projectiles described are early flak ones & some other variants.
Thanks for your reply though , nice ones u show. Don’t see the 2cm A.Z. m.M. very often.
If anyone knows more on the subject , would be greatly appreciated.
