.45 teat fire caliber, 7.5" octagonal-to-round barrel, S/N 4. Blued finish, smooth ivory grips. Six-shot, single action revolver with frame mounted pivoting National patent extractor. Barrel roll marked in a single line: NATIONAL ARMS Co BROOKLYN, N.Y. Matching serial numbers on frame under left grip, forward of triggerguard, under barrel, on the inner side of the extractor, on the rear face of the cylinder and in pencil inside both grips. Production numbers unknown, produced during the mid-1860s using the front loading teat fire ammunition designed to circumvent the Rollin White patent for the bored-through cylinder.
Good. Retains no finish with a mottled and moderately oxidized brownish patina. Barrel marking legible, some serial numbers with wear. Mechanically functional, very good bore with strong rifling. Ivory grips with good age, some minor age related hairline cracks and some minor shrinkage leaving the frame to grip fit imperfect.
