Manufactured in the early 1930s, chambered in the rarely encountered 6.35mm (.25 ACP). These rare pistols are generally seen falling in the 776,xxx-780,xxx serial number range, with this example just outside of that range. Externally nearly identical to the standard 7.65mm PPK except for the caliber marking. The interior shows a set of milled panels inside the slide to compensate for the increased weight of the barrel and aid cycling with the reduced power cartridge, and a correct magazine that is essentially a Walther (Model 8) pocket pistol magazine slotted into a PPK magazine. Standard markings including "crown/N" proofs on the muzzle, chamber, and slide, 90 degree safety, and one piece Walther banner grips.

Fine, retains nearly 70% original blue finish with the balance showing mostly a smooth grey patina from holster/handling type wear and a couple small patches of very light pitting towards the muzzle on the slide. The grip is very good with vertical cracks on the left, a few light handling marks, and otherwise crisp checkering. Mechanically excellent.
