This model was manufactured around 1868 to 1872 and is one of the predecessors of the famous .45-70 Springfield trapdoors. It has the standard markings and features, including two sets of "ESA" and "FWS" cartouches on the left flat. The E.S.A. is for Erskine S. Allen, the inventor of the Springfield trapdoor and master armorer at the armory. A removable collection marking is on the trigger guard bow.

Very fine with 85% plus of the original dark case colors on the breech and vibrant original case colors on the lock, mostly "armory bright" polished finish on the barrel and furniture, some surface spotting/discoloration, strong oiled finish on the very fine stock, minor dents and scrapes in the wood, and general minor age and storage related wear. Mechanically excellent.
