I do not know the back story on it or the maker . Everything points to a German guild maker . I have collected these for years and all are unique and 90 % have no makers mark . Sometimes these are referred to as “ cigarette rifles“ because they were made between the wars, and sold to GIs or trade it for packs of cigarettes, which were a hot commodity in Germany. It’s a cool rifle overall that is built very nicely.
I am trying to figure out what makes you think this was made by a German gunmaker between the World Wars. I have used and seen many sporterized 1903s, but never one that claims this particular provenance.
