I must resist!!
Also, I must add that the BUGNRU proofs, according to Speed, mean that the rifle was returned to Mauser for major repair or alteration.
This is a TypeB (metal wise) made in 1924-25
The 9.3X57 is probably one of if not the rarest chambering in an Oberndorf Mauser and one such rifle is detailed in Speed’s ‘Original Oberndorf Sporting Rifles’ book in which it is assumed that the rifle was returned for a rebarrel to 9.3X57 which was very popular in Sweden. This could be so, I guess, but the stamps on the barrel - serial and chambering - are 100% correct on this rifle and the one in the book so I’m not sure what the major repair or alteration could be but to see two rifles of the same vintage with the same chambering and proofs - quite interesting anyway.
Super cool rifle that is worth the entry fee all day long!
