Reportedly 255,040 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 a simplified single leaf rear sight. This example is dated "1864" on the lock and barrel. 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. The left stock flat is marked with two script inspection cartouches including "ESA" of Erskine S. Allin.

Very good with dull polished surfaces visible on the barrel and fittings, lightly faded markings in the metal, 80% case colors on the lock plate with scattered light freckling overall. Stock is fine as lightly sanded and re-oiled with some light scratches and dents and nice cartouches. Mechanically excellent.
