This is one of 25,000 rifles built using the second variation of the Erskine S. Allin trapdoor system in 1866 using Civil War Model 1863 rifled-muskets. It has the standard markings and features.

Fine with 30% original case colors on the lock, traces of original oil quenched case colors on the breech, and gray patina and some oil straining on the most of the metal. The stock is very fine with sharp edges, raised feathered grain, and has minor handling and storage marks and some chips at the edges of the ramrod channel. Mechanically excellent.
