Manufactured in 1880 as a second model featuring a dust cover rail secured to the receiver by two screws and dust cover with serrations at the rear. The barrel has a dovetail blade front sight and an elevation adjustable buckhorn rear sight and is stamped with the two-line address/patent dates legend ahead of the rear sight. The rifle correctly lacks a caliber designation. The upper tang is marked "MODEL 1873." The lower tang has the serial number. The straight grip stock is fitted with a trapdoor crescent buttplate (cleaning rod not included).
