This exceptional Civil War Burnside breech loading carbine was manufactured by the Burnside Rifle Company in Providence, Rhode Island in 1863-1865. The carbine has the guide screw in the center of the right side of the frame which distinguishes 5th Model Carbines from earlier variations. The carbine has a blued barrel, breechblock, upper and lower receiver tangs and outer breech lever. The barrel band, receiver, hammer, inner breech lever and buttplate have color casehardened finish. The stock and forearm are black walnut with an oil finish. The carbine has a two-leaf folding rear sight mounted on the barrel and sling bar and ring on the left side of the receiver. The top of the barrel is roll-stamped: "CAST STEEL 1864". The top of the receiver is marked: "BURNSIDE PATENT/MODEL OF 1864" The right side of the lock plate is stamped: "BURNSIDE RIFLE Co./PROVIDENCE=R.I." in two lines. The serial number, "17560" is located on the top of the receiver and breechblock. Small single letter sub-inspector marks are stamped on most components. Small "N.S.P." sub-inspection marks are stamped on the underside of the forearm and trigger guard comb. Two script, three-letter Ordnance sub-inspection and final inspection marks with rectangular borders are stamped on the left side of the stock wrist. The Burnside Carbine was a successful and widely issued Federal Civil War cavalry carbine.

Excellent plus. The carbine appears to be un-issued and un-fired. 98% of the blue finish is present on the barrel, breech block and lever. There is some finish wear on the receiver tangs. Virtually all of the case-hardened finish is intact with vivid case colors. The stock and forearm are in excellent condition; wear is limited to some minor storage dents adjacent to the stock sling swivel. The inspection marks on the left stock wrist are extremely sharp. The receiver and lock plate marking are crisp. This is an outstanding, un-issued, example of an important Civil War carbine.
