One of 2,000 Second Model Burnside carbines manufactured circa 1860-62. The second model is an improvement on the first model before it, in that it features George P. Foster's patented breech-latch. The main distinguishing characteristic of the second model from the more common later examples is the absence of a forearm. Lock plate marked "BRISTOL FIREARM CO." and lever catch marked "G. P. FOSTER.PAT./APRIL 10TH 1860" on the right. Serial number "615" marked on top of the frame (partially worn) and bottom of the barrel, and "401" on the period field replacement breech block. Some of these carbines were used by the 1st Rhode Island Infantry at the Battle of Bull Run in July 1861, and the remainder were issued to many Federal cavalry regiments including the 1st U.S. Cavalry. Nearly all of the Second Model Burnside carbines saw hard Civil War service with a low survival rate.

Very good, exhibiting signs of genuine Civil War use with smooth brown patina visible in various areas, and scattered light to mild pitting. Stock is good with added protective coat of varnish, numerous scattered mild scratches and dents, and mostly defined edges. Mechanically fine. This is a solid representative example of a Civil War used scarce Second Model Burnside carbine.
