.52 caliber. 30.5" pinned octagonal barrel. SN: NSN. Bright finish, brass furniture, full-length hardwood stock. Top flat of barrel marked "LEMAN LANCASTER P.A. WARRANTED", lightly engraved commercial percussion lock with no discernible markings appears to be an old replacement as the fit is poor. The rifle was likely altered to percussion from flint as the drum bolster is crude and the lock was probably replaced at the time of alteration. Rifle mounted with a four-piece simple Lancaster style patch box with lower leg broken and missing and relying on an old piece of brass with a screw to hold the door closed. Additionally brass furniture includes the buttplate, toe plate, S-shaped side plate, triggerguard with short spur, nose cap and ramrod pipes. The barrel and stock appear to have been shortened during the period of use, probably between 2" and possibly as many as 12". Lock mounting screws replaced, as is the hammer screw. Fixed notch rear sight and dovetailed Rocky Mountain brass front sight blade. Includes a wooden ramrod.
