Excellent, thanks for your help. Given the condition of this kit, numbers matching, E & D selector and other markings and lack thereof of other signs of export (marks, tig defacing on top cover etc.) I believe this may have been a war trophy originally. The chamber was welded over like you might see from an early form of demill and the receiver has been saw cut removing a small section which is the recent deactivation. The place I got this from sells parts from deactivated guns that they get from police departments I believe. So I think this was "turned" in by someone. I have had about 8-10 of the MP34 kits over the years and this is hands down the nicest.
