Nice find Shamus.

These .303Mausers are rare and with the execption of the barrelprofile is very similar to my .303 Rigby. Your barrel has a stepdown a head of the expresssights mine hasn`t. Other than that this rifle could be a Rigby. These old rifles are very petit and makes all new made boltactioned guns into railroad sleepers by compairision. In a Mauser98 the .303 becomes sort of "Exotic"..
