Here is the "navy" holster that I got on ebay. I have serious doubts about the authenticity of the eagle M stamp on this holster, as it looks much newer than the other stamps, & I cannot find it in Costanzo's book.
The holster is dark brown, stamped KernKl&ger&Cie, 1936, Berlin; DE WaA63, with a Nazi eagle over M. The maker is a Berlin maker that made holsters for the Third Reich, so I believe the maker and Wa stamps to be legit.
I would appreciate any opinions as to the authenticity of this holster.
One of the belt loops has been restiched, but it looks like an old repair
