Is this holster a repro????

[Doubs]

USMC, I have a black, unmarked Luger holster that was purchased in about 1956 - give or take a year or two - with a Mauser Luger in it. It is not a repro. There is a copper rivet repair to one of the belt loops that was likely done in the field. I've always thought that it was a commercial holster. The quality is quite high.
