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 rear sight. 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 muzzleloading arm. "1864" dated at the tail of the lock with the eagle and shield motif and "U.S./SPRINGFIELD" at the center. "1864" dated on top of the barrel at the breech with "V/P/(eagle head)" proofs on the left quarter. The left stock flat is marked with two crisp bordered script inspection cartouches including that of Springfield Master Armorer Erskine S. Allin. "US" marked buttplate tang. Includes a "US" marked socket bayonet. Provenance: The Bob Noske Collection; The David Aroh Collection; The Greg Lampe Collection
