An estimated total of 1,000 New Haven Arms Co. carbines were manufactured between 1857 and 1860 in three barrel lengths. This example has the desirable 21 inch barrel that is a great compromise between the compact 16 1/2 inch carbines with lower capacity and the heavy 25 inch barrel rifles with higher capacity. The Volcanic designs are an important step in the evolution of lever action designs and are among the most iconic mid-19th century firearms. At first glance, the similarities between this rifle and the Henry rifle that followed are evident. The top barrel flat is marked "NEW HAVEN CONN. PATENT FEB. 14, 1854". The barrel is fitted with a rounded German silver blade front sight, and the top of the receiver is fitted with a dovetailed, wheel adjustable notch rear sight. It is mounted with a straight wrist stock with a crescent buttplate with faceted and pointed heel. The upper tang is marked "221," and "211" is stamped on the lower tang, tang screws, and written on the front of the stock. According to "Volcanic Firearms: Predecessor to the Winchester Rifle" by Lewis and Rutter, authorities estimate fewer than one-hundred New Haven Carbines with 21 inch barrels were produced (page 79).

Fine with 70% original blue finish, significant original finish on the small parts, minor patches of pitting, attractive aged patina on the frame and buttplate, minor scratches and dings, and general minor wear. The rear sight is a modern replacement. The stock is fine and has numerous mild scratches and dings, crack in the toe, and flakes at the edges of the wrist. Mechanically fine.
