So I got this gun from a family member that is deceased and was a heavy military enthusiast and probably served around the 70-80s and I was able to acquire a part of a gun that has no serial number or stamps on it, I really thought it was a sub machine gun like an uzi or Mac 10-11 but I realized the mag enters on the left side and the pull back lever is on top, the mag looks like it would hold 9m or .45. I just would like to now what I have and it doesn’t have the trigger, I’m not that educated on guns as I would like to be. Also i feel this might be foreign made or missing a wooden stock or something
