.50 caliber. 42.25" wedge retained octagonal barrel. SN: NSN. Bright finish, brass furniture, full-length hardwood stock with raised cheek rest. Percussion altered flint lock marked "TRYON" weakly. Top barrel flat marked "TRYON . PHILADA". Rifle altered to percussion by Henry Leman of Lancaster with his trademark patent breech, sweeping bolster with clean out screw and percussion hammer with tall spur that seems out of proportion with the balance of the hammer. Equipped with single trigger, dovetailed notch rear sight and dovetailed German silver blade front sight in brass base. Mounted with four-piece plain brass patch box, brass butt and toe plates, thick geometric two-screw brass side plate, chunky finger extension triggerguard, brass nose cap, two ramrod thimbles and an entry pipe. The initials RB are carved into the cheek rest on the reverse butt. Mr. Ness' notes mention that the gun was found in Kansas.
