Manufactured in 1863. 12,501 of these rifles were manufactured by Remington between 1862-65 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 a unique pattern. The "Model 1863 Zouave" nickname is of unclear origins, and whether or not any of these rifles saw use in the war remains unclear and debated. Left side flat marked with boxed script cartouches "HDJ" (Henry D. Jennings) and "BH" (Benjamin Hannis). Brass patch box contains tools and an extra nipple. Includes a saber bayonet and brass scabbard contained in black leather.

Excellent plus, as issued, retaining 98% plus original blue finish on the barrel with some light handling marks. 97% original vivid case colors on the lock. Brass fittings with an attractive original bright color. Wood is also excellent plus with some light handling marks, a few mild scratches in front of the patch box, and crisp cartouches. Bayonet is very fine with some very light spots of pitting on the blade, attractive patina on the brass, and lightly aged leather. Mechanically fine apart from a faulty worn sear spring that causes the hammer to release prematurely.
