.58 caliber. 33" pinned octagon to round barrel. SN: NSN. Browned barrel, brass furniture, faux striped hardwood stock with raised cheek rest. Single screw percussion lock marked "LEMAN/LANCTR, PA". Nocksform of barrel marked "H.E. LEMAN/LANCASTER, PA" and "WARRANTED" with stamped decorative boarder lines. Semi-buckhorn rear sight, dovetailed brass Rocky Mountain sight blade. Plain brass commercial furniture, including finger extension triggerguard, crescent butt plate, toe plate, nose cap and ramrod pipes. Includes a brass tipped wood ramrod. Mr. Ness' tag notes that this is a "rare configuration" and the gun is likely an Indian trade rifle. The form is that of a "smooth rifle" or "buck and ball gun", so it was surprising to find the bore rifled. A very nice, lightweight percussion rifle by Henry Leman.
