New Ross MK2, have some questions?

[Bluenoser]

You have a Ross Mk II***. It was first manufactured as a Mk II**** with a Ross Mk III rear sight. That sight was replaced with the present Canada Tool & Specialty Co. (Sutherland Mk II) sight and the rifle designation changed to Mk II ***. The M.E. Sutherland Sight Co. became the Canada Tool & Specialty Co. That all happened at the factory, and before the rifle left the factory, and the two divots on the under-side of the barrel are remnants of the earlier sight mount.

Your barrel has been set back one turn.
