9/30/19 - This is a police style Walther PPK holster. This holster would also suit a WW2 era Sauer or Mauser police pistol. The holster is only marked with a police eagle stamp under the closure strap. There's an interior "Primosa Stuttgart" ink stamp on the leather as well (place of manufacture). The holster has excellent strong leather and stitching all in tact. Very clean and almost unissued condition. Getting a pistol to fit in this would be tough, but that's to be expected on these old minty holsters.
