Approximately 255,000 Model 1863 Type II, also known as Model 1864, rifle-muskets were manufactured in 1864-1865. These Type IIs are nearly identical to the Model 1863 Type I before it, but now with spring retained barrel bands and typically with a simplified single leaf flip-up rear sight. Ramrod is similar to the Enfield pattern with concentric grooves and slot for a cleaning patch. These rifles are significant in the history of U.S. martial arms, as they armed Union troops and saw widespread use in the latter years of the Civil War. They are the last U.S. regulation muzzle loading arm. These "Model 1864" rifle-muskets are described on pages 333-335 of George D. Moller's book "American Military Shoulder Arms Volume III" with this exact rifle pictured on pages 333 and 335. "1864" dated on the tail of the lock and top of the breech. The left stock flat is marked with two bordered script cartouches including that of Springfield Master Armorer Erskine S. Allin. Includes US socket bayonet and period leather sling.
