This example is marked "NEW HAVEN CONN. PATENT FEB. 14. 1854" on the top barrel flat; the omission of the "VOLCANIC" markings indicates that the pistol was manufactured after Oliver Winchester assumed control of the Volcanic Repeating Arms Co. and reorganized it as the New Haven Arms Co. in April 1857. The New Haven Arms Co. manufactured approximately 3,300 Volcanic pistols and carbines with less than a thousand of the short barreled Pocket pistols produced between 1857 and 1862.
