.60 caliber. 29" three-stage pinned octagon to round barrel. SN: NSN. Oxidized metal, brass furniture, full-length walnut stock. Unmarked single-screw percussion lock, unmarked barrel with drum bolster. Simple brass furniture includes a flat, screwed buttplate, finger extension triggerguard, sheet brass forend reinforcement and nose cap and a single corrugated pipe securing a wooden ramrod. Larry Ness' notes identify this as Leman's "first attempt" to produce a percussion trade gun and further notes that when these guns were sent to Nebraska, South Dakota, Montana and Wyoming for trade that the Natives "threw them on the ground in disgust". This is a lightly made, poorly finished gun that would certainly be less than popular with Natives used to receiving the much higher quality arms made by the British.
