12,501 of these rifles were reportedly ordered from Remington by the Ordnance Department between 1862-1865 during the Civil War, per "Flayderman's Guide" (9th Edition, 5E-076). 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. The Model 1863 "Zouave" nickname is of unclear origins, and whether or not any of these rifles saw use in the war remains unclear, although they are still considered to be a secondary issue Civil War arm. "1863" dated lock and barrel. "R.K.A." (Remick K. Arnold) inspection initials marked on the left barrel flat at the breech. Bordered script "HDJ" (Henry D. Jennings) and "BH" (Benjamin Hannis) inspection cartouches stamped on the left stock flat. Includes a brown leather sling, and the patchbox contains an extra nipple and ball extractor tools.
