This is an excellent example of a very early Walther PP semi-automatic pistol with rare and highly desirable "SA-NSDAP Gruppe" marking on the front grip strap. The SA-NSDAP presided over "28" different SA Gruppes in Nazi Germany, with all of them relying on Walther to supply their organizational marked pistols. Each Gruppe or districts markings were panagraphed on the grip strap, with some Gruppes having numerous pistols while other smaller Gruppes had considerably fewer pistols. The very few examples that are seen today in the U.S. were probably captured on the western side of Germany, with those in the east captured and destroyed by the Russians. These are really a very scarce pistol with not many examples actually in the U.S. today. This wonderful example is marked on the front strap: "SA der NSDAP/Gruppe Neiderrhein". The left side of the slide is marked with the Walther banner followed by "Waffenfabrik Walther, Zella Mehlis (Thur)/Walther's Patent 7.65m/m, MOD PP". The right side of the muzzle, chamber and slide are marked with pre-War commercial "Crown/N" proof with the serial number (103931P) marked vertically on the right side of the frame behind the trigger. It has fixed sights, Walther marked blue magazine with black plastic finger extension and Walther banner on the left and is fitted with black checkered grips with the Walther banner at the top.
