I've come to believe that this rifle was built as a Wimbledon style "bull gun". I found this article about a Wimbledon "Bull Gun" made by Griffin and Howe for Ben Comfort, who won the 1935 Wimbledon match with it. Comfort's rifle was chambered in 300 H&H and was built on a Remington model 30 action, which bears a strong resemblance to a 1917 action. I've read, however, that prior to Comfort's Wimbledon cup win, most "Bull Guns" built for Wimbledon competition were chambered in 30.06 (like my rifle) and many were built on the 1903 action.

The barrel profile, although chambered in 300 H&H mag rather than 30.06, appears to be very similar to mine.







Muzzle seems very similar to mine also.



Damascene markings on the bolt seem similar
