A nice early Walther RZM marked PPK manufactured in 1934. The RZM was the National Material Control Office for the NSDAP, and was responsible for purchasing uniform related items of which the PPK was one. The pistol was a badge of rank for the Political Leaders of the NSDAP.
This one was bought several years ago at a small show, and was in a nondescript black pebble grain holster that did not fit. After I had bought it the seller was about to walk away when he ask if I needed a spare holster. In his jacket pocket he had the original Akah holster, and when I got home I found that the original capture papers were folded and stuck in the spare magazine pocket.
