"Very Unusual 2nd Model Burnside Carbine Converted to Cartridge (AL5257)
"Overall length is approximately 40". The 21" round approximately .62 caliber (20 Gauge?) smoothbore barrel has a fair bore. The barrel is gray with dark spotting. The nickeled receiver and action have approximately 70% nickel with the remaining a brown patina. The buttstock is very good with use dents and dings but no cracks or chips. The butt plate is brown with some roughness. The sling bar and ring are absent. The lock has the early Bristol Firearm Co. marking. The breech block lever is marked “G.P. Foster pat/ April 10th 1860". There are no barrel markings. In addition to the barrel being bored out to smooth bore, the breech block has been extensively modified. The Burnside cartridge cavity has been removed and replaced by a spring-loaded firing pin that is actuated by the original slightly modified hammer. The breech block now has a recessed face with a center firing pin hole. The action functions correctly with the exception that a trigger pull will release half cock. The sling swivel on the bottom of the buttstock has been removed but the escutcheon remains. Only about 2000 2nd model Burnsides were made. When combined with the centerfire conversion, this gun is most likely unique. It would fill that pesky hole in your civil war carbine collection and is also an interesting example of an early cartridge conversion.
