I ordered 2 KP44 parts kits with 2 Suomi drums and a repair channel from Military Gun Supply. I got the package today. When I opened it, I did, indeed, have the 2 drums and repair channel, but the kits are for some gun I cannot ID. One of the kits was complete, except for the receiver, but the other one only had the "lower receiver" with underfolder still attached, barrel shroud, and some receiver chunks. Nothing else. Help me out here. What did they send me?
