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 "HDJ" (Henry D. Jennings) and "BH" (Benjamin Hannis). "H.S.L" (Homer S. Lathe) inspection initials marked on the left barrel flat at the breech.

Exceptionally fine, retains 95% plus original blue finish on the barrel with a noticeable dent visible on the right side ahead of the bolster, some light thinning around the muzzle and strong patterns of approximately 60% muted original case colors visible on the exposed surfaces of the lock and hammer with vivid case colors in the protected areas, and sharp markings and edges in the metal overall. The brass exhibits a pleasing golden aged patina. The stock is very fine with distinct edges, a few light scratches and dents, and crisp cartouches. Mechanically excellent. A solid representative example of a Remington "Zouave" rifle that would make a fine addition to any U.S. martial or Civil War firearms collection!
