An interesting connection in the evolution of lever-action repeating firearm, is found in the production of a small group of pistols and rifles built in Norwich, Connecticut, by Horace Smith and Daniel Wesson under the firm name of Smith & Wesson. Company built two types of Volcanic pistols. One was a large-frame model, with 8" barrel chambered in .41-caliber. About 500 large-frames were built. The other was a small-frame version, with 4" barrel chambered in .31-caliber. About 700 small-frames were built. In both variations the barrel, magazine and frame were blued. Smith & Wesson also produced a lever-action repeating rifle. These rifles are exceedingly rare, with fewer than 10 having been built. They were chambered for .528-caliber and fitted with 23" barrels. Because of the small number of rifles built, no value is offered. The same Volcanic action was later used by Volcanic Repeating Arms Co. and Winchester predecessor New Haven Arms Co. (listed below). All Volcanics fired caseless self-contained ammo rounds called "rocket balls" consisting of a lead bullet with the power loaded in the hollow base, and a primer attached to the base. They are fed from a tube magazine mounted underneath the barrel.
