.58 caliber. 33" barrel secured by two solid, rounded spring-retained barrel bands. SN: A2. Bright finish, steel furniture, brass triggerguard and lock screw escutcheons, pewter nosecap, walnut stock. Single shot percussion ignition muzzleloading military rifle. Lock deeply marked in a single line E. WHITNEY along the lower edge, under the bolster. Barrel numbered A2 under the muzzle. Rifle retains the Whitney "Mid-Range" leaf rear sight, base and blade front sight, saber bayonet lug 4" from the muzzle, both sling swivels and an incorrect cut down Austrian Lorenz ramrod that may be a period of use replacement. The initials JM? are lightly carved in the obverse stock. While this pattern of "Enfield" style rifle was previously categorized as a "Type IV" by Flayderman, more recent and detailed scholarship by George Moller classifies them as "Type III" rifles. Moller further notes that the approximately 775 rifles of this pattern produced by Whitney were likely Federal purchases via Schuyler, Hartley & Graham.
