1936 Mauser 42

Thor thanks for the help. Ok I'm getting confused now so let me try to clarify a few things.


First the photo is of SteveM's gun, not mine, I posted it for reference only since it so closely resembles mine.


Second. The serial number of my gun is actually 9221 and the 21 is in all the places on the (left) side of the gun.


Third, Looking down on the gun, starting with the barrel it reads 1936, then the 42 (opposite direction) and then the 79 facing the same direction as the 1936 but almost to where the knobs are. Then there is a small 79 on the place where you might rest your thumb.


So is the top half of my gun from another one? The barrel has the correct serial number too.


I don't know how you guys keep this stuff straight for all these guns. Thanks again.
