Interesting about the Arnhem related grenade launcher.............and how that ended up in the Balkans. Must have gone with German troops when pulled back into Germany, and someone took it east, and it got swept up with the 1000's of others captured by the USSR at war's end. May have been in use by East Germany early on after the war, before ending up in the Balkans. I wonder what the date and factory code is on the top of the receiver, and whether its all matching or not?
