I recently had the luck to acquire a lovely rifle in very good original condition.
What makes it unusual (to me at least?) is the sight setup. There is a tangent type rear sight which runs in dovetail grooves along the barrel with numbered positions. There is also a cutout where the whole sight can be removed.
There is also a dovetail on the receiver top which at first one would think is for a scope, but the bolt handle is not designed for scope use, so could this have been for a peep sight or some such? (I've since seen pictures of Mauser raised scope rings with holes to see the iron sights through them as well as a diopter sight set-up which work on these dovetails)
The engraved writing consists of:
PATRONE 22 LONG RIFLE Serial no is: 123143 Proof marks are crowns over B U & G Mauser Werke AG Oberndorf An.
And letters that seem to be DRP DRGM. Any further info would be appreciated!
