These "Fifth Model" Burnside carbines represent the completion of the evolution of General Ambrose Burnside's ingenious carbine design. The outbreak of the Civil War led to the purchase of over 50,000 Burnside carbines. They were the third most purchased breech loading carbine during the war, after only the Sharps and the Spencer. This example has the matching serial number on the frame and breech block, single letter inspection marks on various components, boxed script "EPR" and "RKW" inspection cartouches stamped on the left stock wrist, and "N.S.P." inspection initials ahead of the buttplate tang.

Excellent, retains 98% original blue finish on the barrel with very light muzzle wear, some areas turning to a smooth brown, and some very light surface freckling, 90% plus bright original niter blue finish on the breech block, lever and tangs with some light freckling and flaking on the tangs, and 90% original case colors on the frame, hammer, lock, lever latch and buttplate. Wood is also excellent with attractive original raised grain and rich oil finish, defined edges, a few scattered small dings, and mostly crisp cartouches. Mechanically excellent.
