Hello all. I have a Walther P38 that I do not know much about. The slide is marked AC41. The serial numbers on the slide and the frame do not match. The slide has a serial number 26XX and the frame has a serial number 24XX. Here is the weird stuff. The serial numbers on the frame and on the slide have been crossed off. The new serial numbers are matching and they are 55XX. The place where my dad got it from said that it was captured by the Russians in the course of WWII. Could you tell be more about it please? Also a DOB would be nice.
