Manufactured in 1883 as a third model with integral dust cover rail, dust cover with rear serrations, and standard markings including the lack of caliber markings. The only chambering initially offered for the Model 1876 was .45-75, making a caliber marking unnecessary, a practice which appears to have sporadically continued well after other calibers were offered. Fitted with German silver dovetailed blade front, folding ladder rear, and tang mounted peep sights. Mounted with a smooth forearm and straight grip stock with a trapdoor crescent buttplate (cleaning rod not included). The included factory letter confirms the current configuration as well as receipt at the warehouse on 4 September 1883 and shipment on 27 August 1884. Also included are two schematic prints of the .45-75 W.C.F. cartridge and a spent Jamison .45-75 casing.
