These "Fifth Model" Burnside carbines represent the completion of the evolution of General Ambrose Burnside's ingenious carbine design. The Burnside carbines were the third most purchased breech loading carbine during the war, after only the Sharps and the Spencer. This example has standard markings and features, including matching serial numbers on the frame and breechblock.

Fine with 60% original blue and bright niter blue finish, 25% original case colors, dark brown patina on the balance, mild pitting mainly on the right side of the frame and rear of the lock, and general mild overall wear. The wood is very good and has moderate scrapes and dings, a rectangular patch on the right side of the buttstock from a label, and some loss at the heel. The lock needs work (not locking up at half or full-cock), but the carbine otherwise mechanically functions fine.
