.35 caliber. 37.75" double key octagonal barrel with under rib. SN: NSN. Browned finish, German silver furniture, half-stock figured hardwood stock with checkered wrist. Barrel marked "TRYON PHILADA". Back action percussion lock lightly engraved and marked "H ELWELL". Double set triggers. Mounted with engraved German silver furniture including a four piece rudimentary pineapple finial patchbox, a flat bottom triggerguard with finger spur, buttplate, toe plate, entry pipe, nose cap, wedge escutcheons and two blank oval plates at the thumb plate and counterpane positions. Two steel ramrod pipes are attached to the bottom lug of the barrel, continuing a modern steel ramrod. Dovetailed fixed rear sight and dovetailed German silver front sight blade. The name H. ELWELL is that of an unidentified lock maker, but his locks do appear on a variety of mid-19th century rifles. Tryon was one of the leading Philadelphia gunmakers during the mid-19th century and produced everything from contract military arms to high grade sporting arms. This was a relatively high grade gun when new and is a very attractive half stock percussion rifle with very nice German silver furniture.
