WW2 German holster with eagle badge

Here is a leather holster that I believe for German ww2 sidearm. It has the national eagle for the national party affixed to the flap with bent over brass tabs that show green oxidation from age. Fits a Walher PP pistol as shown but would take many other models. I can find no markings on it. Leather and stitching is very good condition for the age. I cannot guarantee the actual age or origin, but interesting piece either way.
