Approximately 30,000 were manufactured by the American Machine Works in Massachusetts from 1861 to 1865. Some of these carbines were issued to the 3rd West Virginia Cavalry, who served as part of George Armstrong Custer's 3rd Division and played a pivotal role in the Battle of Moorefield in 1864. This carbine is in very fine condition with standard markings and features including "JH" cartouche on the left of the stock.
