But it's not a Martini Henry, it's a Peabody Martini. A Turkish M1874 Type A. Built in Providence, Rhode Island, USA, shipped to Turkey, lost to the Russians in the Russo-Turkish War of 1877-1878, then sold to the Japenese for use in military schools. It has markings in English, Arabic and Japanese. I'd guess it returned to the U.S. sometime after WWII.
the marks on the receiver:
and the other side, with the action open:
A pretty neat wall-hanger, I think.
