Breakaway holster with a typical curved lateral flap designed for the WALTER PP pistol.
This one presents a black finish but it also exists in brown.
Markings : on lateral flap, the DRGM with a faint AKAH logo. The inside ink markings are not present any more.
The same holster (in brown !) is detailed in the book WW2 German Military Holsters on page 148.
