Don't know what it is, but it is not German.
Thanks Sarge, for reference what makes it not German? The studs? The only thing that looks like it is, PPK Holsters,though i havent found one with the same back with those studs
The whole style is wrong. I'd almost say it is post war russian or another east block country.
The markings remind me of those I've seen on ruskie holsters.
Like Sarge states it is East block all right. A post war DDR (German Democratic Republic) Makarov holster, I would say.
If you google that, you'll find plenty of pics.
Thanks Emileverbunt, certainly similar although i cant find an exact match under Makarov..and being DDR makes sense as it has the name Lange on it
