J. Stevens Arms and Tool Company.
The firearms made by the J. Stevens Arms and Tool Company, Chicopee Falls, Mass., has a wide reputation. A full line of rifles and pistols were exhibited, as well as the Stevens single barrel shotgun. One of the novelties was the rifled bullet shell for shotguns. This was shaped like brass shell with a short rifle, or rather pistol barrel extension. The shell fitted into the chamber of a shotgun, and for emergency would convert a shotgun into a rifle without any more effort than inserting an ordinary shell. This rifled bullet shell was made in 10, 12 and 10 gauge, can be used in single or double guns, and are made in different calibres.
