I have two pistols given to me by my great uncle. He was in WWII and the pistols are in a box with Walther PPK mit Signalstift inscribed on it. Neither pistol is marked with the Walther banner logo. The .32 has a S/N of 2622 on the frame and on the underside of the barrel. Inside the magazine housing at the top is the number 4953 and at the bottom of the housing are the letters O.W. The grips are plastic and unremarkable except for the letter O at the top of each grip. The other is marked with CAL .635 at the top of each grip with what appears to be an engraving of some sort of jungle-dwelling native type. On the slide are the words AUTOMATIC PISTOL FAVORIT and the S/N is 39065. On the frame are the encircled letters P and X with letter C in between them. The encircled P is also found on the barrel. Once again, neither pistol is labeled as to the maker. I have dismantled and re-assembled both and found no other markings, and the .32 has been used at my local range. I don't know if these were acquired from a member of the German military but it seems as if the original pistols in the box were replaced with the current ones. Any thoughts on the possible manufacturer and date would be appreciated.
