ヘンリー銃
After Smith's departure, Benjamin Henry continued to work with a Smith development project, the self-contained metallic rimfire cartridge, and perfected the much larger, more powerful .44 Henry round. Henry also supervised a new rifle design based loosely on the Volcanic to use the new ammunition, retaining only the general form of the breech mechanism and the tubular magazine. This became the Henry rifle of 1860, which was manufactured by the New Haven Arms Company and used in considerable numbers by certain Union army units in the American Civil War. The Henry rifle ensured New Haven Arms' success, and together with the Spencer rifle, established the lever-action repeater in the firearms market.
