Approximately 273,000 Springfield Model 1863 Type I rifle-muskets were manufactured c. 1863-1864 with the screw fastened barrel bands. 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. Solid blade front and 500 yard two-leaf rear sight, "1863" dated barrel with "V/P/eagle head" proofs, and casehardened "1863" dated "U.S./SPRINGFIELD" marked lock with the Federal Eagle. The left stock flat is marked with two bordered script cartouches including one of Springfield Master Armorer Erskine S. Allin. "US" marked buttplate tang. Includes a "US" marked socket bayonet.

Very good with bright surfaces on the barrel and components, the casehardened lock assembly turned to a smooth brown patina with traces of case colors on the hammer, scattered light freckling, and defined markings and edges in the metal. Stock is also very good with scattered dents and scratches, and visible cartouches. Mechanically excellent. Bayonet is also very good with scattered oxidation.
