Nice! Looks to be a clean one. Be curious as to the bore size. I've been told that the 1910s varied a lot in their bores.
Is there a more confused cartridge than the 9.5x56M/S, aka 9.5x57M/S, aka .375 Nitro Rimless, aka .375 2 1/4, aka etc, etc?? What makings for such a great cartridge, yet the confusion continues a century later.
At any rate, nice rifle and that little A/N is a sweetheart as well.
