Nice soft shell holster designed for some 7,65 mm pistol dated from the COLD WAR.
It is made in shiny black leather.
Markings : on rear face, a typical Austrian Police marking = Eigentum des Wien Sicherheitswache and Wien inscribed in an oval.
It looks like a WW2 German or Austrian holster but is not !
This holster is detailed in the book WW2 German Military Holsters on page 78.
