I have the above mentioned rifle that I believe to be a Mark 1 as it has a cutout in the middle of the bridge for the "Pederson" device. I'm thinking of a build for this rifle and want to retain the original bolt handle and wing safety so the use of open or peep sights will be required.
First thoughts were a 500 Jeffery but will require a bit more work than I'm probably prepared to go with at the moment....
