Judging by the saddle style, this unidentified cowboy was working in the late 1870s or 1880s. In his holster, he carries a Colt model 1873 single action revolver with hard rubber grips, and he has looped his left arm around a Winchester model 1873 carbine in a saddle scabbard. On the back is the light pencil inscription “Indian fighter.”
