After the Civil War, the U.S. Government and state militias had stockpiles of leftover muzzle loading rifle-muskets, and sought ways to convert them into breechloaders for use with metallic cartridges. This rolling block rifle-musket is marked with serial number "6" on the left of the upper and lower tangs (hidden by the stock), right of the lower tang, left of the barrel at the breech, on the extractor, rear face of the forearm, and front face of the buttstock. The barrel is sleeved to .50 caliber. The Remington address and patent marking is marked on the upper tang. A "GDM" collection mark is at the toe. Includes US socket bayonet and leather sling.
