47,115 Model 1855 rifle-muskets were manufactured at Springfield Armory between 1857 and 1861, and another 12,158 were produced at Harpers Ferry. They were widely used in the Civil War and first saw action in the Coeur d'Alene War in the Pacific Northwest in 1858. The unreliable and easily damaged tape primers were the main complaint and were abandoned for the otherwise similar Model 1861. It has the standard markings and features for this period in production and includes a socket bayonet with scabbard.

Very good with gray patina, mostly light pitting, minor scratches and dings, and distinct markings aside from the cartouche on the stock which is very good and has minor hairline cracks and chips at the lock, a few other minor chips, and general small dings and scratches. Mechanically fine.
