It sounds like a wartime holster, being pigskin, But it is Very Unlikely that the markings were X'd out by a post war European user. Not a lot of that stuff got used in the post war years and what did was appearently not fooled with. The reason I say that is that items such as yours are almost totaly unknown. It it had been the practice of some govt then there would have been a lot show up in later years on the surpluss market when they went to other weapons or different leather.
