I have a few dewats or non firing guns My first is actually an M2 carbine the action is welded shut and there is a section of the barrel that is actually a piece or ordinary hardware store threaded Rod. from the chamber to just before the barrel emerges from the stock and handguard. on the operating handle there is engraved 50th anniversary 1941-1991, I have Mk III Sten, a Beretta 9mm smg 38-44 I think and a schmeisser mp40, when I was young i could have easiky picked up[ a Piat, a Boyes antitank rifle and a panzerschreck they were all cheap and no one wanted them. they also had be de-militarized.
