I’ve been collecting German militaria since 1976. I clearly remember when the East-West Berlin wall fell, I believe in 1989 or so, that many hundreds or probably many thousands of WW2 German holsters and related militaria were released from Russian East German storage locations, where they had been kept since they were captured at the end of the war. Holsters that had previously been considered rare, for example the GXY1945 softshell P-38 holsters, came onto the American collector market through dealers and gun shows in large quantities, and at bargain prices. All legitimate, most in mint, unissued, as-captured condition. Like from a time capsule. They had been stored in Russia like stacked ice cream cones, closure flaps open, one inside the next, to the point that the metal closure stud of softshell holsters often created a slight pressure dimple in the leather of the adjoining holster, often a telltale indication to collectors that it wasn’t an individual vet bringback, but rather from bulk Russian storage. The softshell holster in the photo from the OP certainly looks like one of those originals. Of course an in-hand exam would be helpful, but I’m just offering my $.02 regarding the existence of large quantities of legitimate WW2 German equipment, such as holsters, that flooded the American market, not 10-12yrs ago, but more like 30yrs ago.
