12,501 of these rifles were manufactured by Remington between 1862-1865 during the Civil War for the Union. Government records listed them as "Harpers Ferry Pattern" rifles, and they have similarities to both the Model 1841 and Model 1855 rifles that were manufactured at Harpers Ferry prior to the Civil War but are of a unique pattern. Whether or not any of these rifles saw use in the war remains unclear and debated. "1863" dated lock and barrel. Left stock flat marked with boxed script inspection cartouches "GP" (Giles Porter) and "BH" (Benjamin Hannis). "B.H" inspection initials marked on the left barrel flat at the breech. Brass patch box contains an extra nipple. Includes a brass handled saber bayonet marked with "BH", "C", and "P" inspection initials, and brass tipped leather scabbard.

Very good, retains half of the faded refinished blue finish on the barrel with smooth brown patina on the balance, obliterated date marking on the replacement barrel tang, smooth gray patina on the lock, scattered light to moderate freckling overall, and mostly defined markings on the lock and breech of the barrel. Stock is also very good with some light scratches and dents, a few chips in the ramrod channel, and defined edges overall. Mechanically excellent. Included bayonet is very good, scabbard is fair with age related cracking and wear.
