Dear T (etc);
Several of us (Seinen, Edokko, etc) are working on a book covering the Japanese weapons purchases, use and modification during the approximate 1850-1900 time period, exclusive of Muratas. Naturally, your Snider comes within our area of interest. Could you send me some additional photos of your rifle, especially any additional Japanese markings, and any other info on your rifle that you think would be of interest? I would appreciate your input.
Also, on the IJN, the small private navies of the Hans (clans) were incorporated into the then new IJN at the time of the Meiji Restoration. Really interest stuff. They even purchased a ex-Confederate States of American warship, the C.S.A. Jackson, which the U.S. seized as it arrived in Cuba immediately after the Civil War was over. The Dutch and then the British helped in the evolution of the IJN. Someone should write a book about the IJN's evolution.
