These "Fifth Model" Burnside carbines represent the completion of the evolution of General Ambrose Burnside's ingenious carbine design. Unfortunately for Burnside, he profited little, if at all, from the his well-known design because he was forced to sell his shares before the company received sizeable government contracts. The outbreak of the Civil War led to the purchase of over 50,000 Burnside carbines. They were the third most widely purchased breech loading carbines during the war after only the Sharps and the Spencer. This high condition example has the standard markings and features, including matching serial numbers and crisp government inspection markings.
