Model 1855 rifles are described in depth on pages 260-267 of George D. Moller's book "American Military Shoulder Arms Volume III", with this exact rifle photographed on page 265 under the description for the Type II variation. According to page 266 of Moller's book, approximately 3,772 Model 1855 Type II rifles were fabricated at Harpers Ferry c. 1859-1861. Page 265 states, "...the distinction between Type I and Type II arms of the Model 1855 series is generally predicated on the type of rear sight used..." The iron cover assembly is of the same configuration as the Type I rifle. However, the stock recess beneath is oval, without provision for the riflemen's sight. It is drilled for a spare nipple, and carries the ball screw and wiper." A limited number of Harpers Ferry Model 1855 rifles saw heavy use throughout the Civil War, and many were destroyed when the factory was burned in 1861. This example has iron fittings, dated "1859" on the lock and barrel tang with the standard front sight/bayonet lug, 500 yard Model 1858 two-leaf rear sight, standard lock and barrel proof markings, marked "112" on the bayonet lug, marked "H/63" on top of the rear band, marked "24" on the barrel tang, and "US" marked on the buttplate tang. Includes a saber bayonet marked "JB" and "47" on the flat of the hilt, brass tipped leather scabbard, leather sling, brass tipped wood tampion, nipple and tools in the buttstock.
