This factory cased Volcanic Pistol-Carbine was manufactured by the New Haven Arms Company circa 1858 using components produced by the Volcanic Repeating Arms Company. The New Haven Arms Company did not manufacture pistol carbines as a regular production item. Pistol-carbines with New Haven Arms Company markings are some of the rarest Volcanic firearms. An unknown but very small number of unfinished Volcanic Repeating Arms Company pistol-carbines were finished and sold by the New Haven Arms Company following the reorganization of the company by Oliver Winchester in May 1857. Very few New Haven Arms marked pistol-carbines have original factory cases. This pistol-carbine has a .41 caliber, 16-inch, octagon barrel with integral 20-shot magazine, brass receiver and cocking lever with round finger hole. The back strap has a single hole to accept a detachable shoulder stock lug and a small alignment pin. The pistol butt has an inverted, knurled, round head, adjusting screw. The attachable stock is straight grain American walnut with piano finish, blued attachment lug and silver-plated crescent buttplate. The blued Volcanic Arms barrel has a crowned muzzle and rounded T-bar with full rib and 2.65-inch magazine block. The barrel has a nickel-silver, pinch-back, front sight. The magazine has a small, clam-shell shaped follower. The top barrel flat has the altered Volcanic Repeating Arms marking: "REPEATING ARMS CO./PATENT NEWHAVEN CONN. FEB. 14. 1854" in two lines. The first line is faint, and the second line is sharp. The brass receiver has an ejection port with square front and rear edges and dove-tail mounted, carbine-style rear sight. The hammer has hand-cut knurling on the spur. The receiver has a natural brass finish, and the hammer, trigger and lever are color casehardened. The two-piece grips are piano-finished walnut. The serial number, "402", is stamped on the right side of the loading lever, the left side of the frame underneath the grip, on the inside of both grips and the top of the stock buttplate. "49" is stamped on the inside of the stock beneath the buttplate, the inside of the buttplate and the shanks of both hand-fitted buttplate screws. This extremely rare carbine is complete with an equally rare factory case. The walnut, American style case is lined in red velvet and has five compartments including space for a cleaning rod or spare magazine spring and ammunition tin. The case is complete with an ammunition tin with black japanned finish and paper New Haven Arms label glued to the inside of the lid. The tin contains six .41 caliber "Rocket Ball" cartridges.
