In "American Gunsmiths" by Frank Sellers "SMITH, F.," maker of a 3 barrel percussion rifle, is listed as unlocated. He also lists a Frederick Smith of Sulphur Springs, Ohio, and one or two men of the same name active in Union Springs and Fleming, New York. The barrel rib is marked "F Smith" accented by a floral motif, and the locks are both signed "Smith." The upper smoothbore barrels are 16 gauge, and the lower rifled barrel is .36 caliber. The shotgun barrels use the conventional side locks, and the rifled barrel uses an underhammer powered by the trigger guard which acts as its mainspring and triggered by a lighter pull on the right trigger. Cocking both the right hammer and the underhammer and only pulling the trigger gently will only fire the rifled barrel. Thus all three hammers could be cocked at once and then fired in sequence. The rods are fitted to the sides of the rifled barrel, and the forend has a pewter cap and silver wedge plates. The other furniture is all iron. The stock has a checkered wrist and attractive figure in the butt.
