Approximately 2,020 Harpers Ferry Model 1836 Hall carbines were manufactured c. 1837-1840. The Model 1833 and 1836 carbines are historically important in being the first percussion arms adopted by the U.S. military. The ramrod bayonet was first experimented on the Model 1833 and 1836 Hall carbines, and was later revived on the Springfield Model 1880 and 1888 Trapdoor rifles, then again on the early Model 1903 rifles. These carbines were used by the 2nd U.S. Dragoons during the Seminole Wars in Florida in which they were exposed to harsh conditions, contributing to their scarcity today. Though largely overshadowed by other 19th century conflicts, the fight against the Seminoles was the longest and most expensive Indian war in U.S. history. Marked "J. H. HALL/US/1839" on the breech block with most of the standard markings and features including a triangular sliding ramrod bayonet, .64 caliber smooth bore, offset blade front sight and V notch rear sight, and a sling ring mounted at the left of the wrist.
