Nash Buckingham and/or his family had a couple Winchesters. The 1893 that Nash and/or Miles won, supposedly upgraded to 1897 specs --
Apparantly, Harold Money left his Winchester Model 1897 with Nash when he returned to England circa 1910, and then went off to manage a rubber plantation in Ceylon. After serving his King in The Great War with the Loyal North Lancashire Regiment, where he advanced through the ranks from 2nd Lieutenant, to Lieutenant, and then Captain, Harold returned to the U.S. in the 1920s and worked at A & F in New York. He apparantly got his Model 1897 back from the Buckinghams at that time, as Charles Wicks mentions him having it.
There are several pictures in Nash's books of Irma with a Model 1897. Whether it is one of the two previously mentioned guns or another, I don't know.
