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 stamped with two boxed script inspection cartouches. "B.H." (Benjamin Hannis) inspection initials marked on the left barrel flat at the breech with "US/VP" and an eagle head proof on top.

Very good, retains most of the custom refinished blue finish on the barrel with some patches of light pitting visible underneath the finish, gray patina on the lock and hammer with some freckling and pitting, and bright golden patina on the cleaned brass. Refinished stock is also very good with scattered dents and scratches. Mechanically excellent.
