.48 caliber. 36" pinned octagonal barrel. SN: NSN. Bright finish, brass furniture, walnut stock. Commercial flint lock is marked "H.T. COOPER/NEW YORK" under the fenced and bridled iron pan with a flat faceted swan neck cock. Lock in original flint with the matching mating number 9 on most internal lock parts, including the cock. Barrel marked "J HENRY" on top flat. Rifle mounted with four-piece brass patchbox with rudimentary Fleur-de-lis finial, extended finger rest brass triggerguard, flat geometric brass side plate, brass buttplate, toe plate, nose cap and ramrod thimbles. Dovetailed fixed buckhorn rear sight and dovetailed Rocky Mountain German silver sight blade. Forend restored from behind the rear sight to the forend cap. Typical form of a J Henry trade rifle of the period, particularly the patchbox, with the one of this style that is illustrated in Jim Gordon's Great Gunmakers for the Early West having been cut to half-stock length and altered to percussion. Like this rifle, that example uses a commercial lock, in that case marked "Spies".
