These Colt muskets were produced throughout the Civil War under contract with the Union and state governments. An estimated 100,000 muskets were manufactured by the end of the war. Many were also sold privately through Schuyler, Hartley & Graham. This model is based on the Enfield Pattern 1853 and has many features incorporated in the Springfield Model 1863. This 1863 dated example has the standard markings and features. It also has "H.B" marked on the bolster above the eagle motif. The meaning of this marking is not clear, but it may be an additional inspection mark by inspector Horace Burpee.

Fine. The metal surface remain mostly bright and have some slight pitting and spotting. The wood is also very good and has some small nicks and scratches, a few bruises, a fresh cut ahead of the front lock screw, and partially faded cartouches. Mechanically fine, and the markings are generally crisp.
