This Volcanic lever action carbine was manufactured by the New Haven Arms Co., c. 1858-59. The carbine has the extremely rare, 25-inch barrel with integral 30-shot magazine. Reportedly, twenty carbines with 25-inch barrels have been identified by collectors (these are sought after due to compatibility on rifle rack with Henry rifles). The carbine has the distinctive brass receiver and crescent buttplate with standard factory scroll and leaf engraving and extra cost silver-plated finish. The barrel/magazine was originally blued and the straight grain walnut stock has a high polish piano finish. The top barrel flat is stamped with the New Haven Arms Company markings: "NEWHAVEN CONN. PATENT FEB. 14.1854" in one line. The serial number is stamped on the lower left side of the receiver tang, on the stock comb beneath the buttplate, on the inside of the buttplate heel and on the shanks of both hand-fitted buttplate screws. All of the visible serial numbers match. The Type III barrel has a nickel-silver front sight, rounded T-bar spring and small brass magazine follower. The receiver has oval cut-outs on the front and back end of the ejection port and is fitted with a dove-tail mounted rear sight with elevation wheel absent. The bolt has a single hook extractor. The hammer has a hand-knurled spur. The top of the receiver and tang, the receiver sides, sideplates, and buttplate heel are decorated with open scroll and leaf factory engraving with dash borders, which was standard on New Haven Arms lever action carbines. The engraving is simple but well executed.
