I acquired a Walther PP, which is either pre-war or war manufacture, since it has "Waffenfabrik Walther, Zella Mehlis (Thur)" inscribed on it, indicating manufacture at the original Walther factory. What is unusual is that the magazine catch is located in the handle. My study of firearm references indicates that the PP and PPK magazine catches are supposed to be behind the trigger guard. The pistol is in 380 ACP. It does not have any German Military acceptance marks. the Serial No is 119256P. The bore is in as new condition, but the surface does have some wear and rusting. It has the smoothest trigger pull I have ever seen in a pistol, and functioned flawlessly when I test fired it. Can anyone give me any further information? Any information about this unusual Walther PP variant will be appreciated.
