Manufactured in 1881. This rifle has a "transitional" receiver that is a second model receiver with the dust cover secured by a small screw on top; however, it is fitted with a later third model dust cover without the checkered oval with serrated edges. Standard sporting style front sight with nickel-silver blade and folding leaf rear sight marked "1876." The upper receiver tang is factory drilled and tapped for a sight, and the crescent steel buttplate has a sliding brass trapdoor (cleaning rod not included). The stock and forearm are varnished straight grain American walnut. The top of the barrel has the two-line address/patent dates ahead of the rear sight. "CAL 45-60" is roll stamped on the top barrel flat immediately ahead of the receiver. "45-60" is roll stamped in script numerals on the cartridge elevator. The upper receiver tang has "MODEL. 1876" in fancy letters with foliate devices at either end. The serial number is stamped in script numerals on the lower tang.
