The Joslyn rifle was the first breech loading metallic cartridge rifle manufactured at a U.S. national armory. 3,007 were assembled in January to June of 1865 utilizing breech units supplied by the Joslyn Firearms Company. More than half were exported to France in 1870 and used in the Franco-Prussian War. It has standard markings and features. It is marked "1864" on the lock, "M/480" on the breech, and "480M" on the tang. A socket bayonet with scabbard and frog is included. The latter has two maker stamps.

Good with a mix of bright iron and mottled gray and brown patina on the barrel, dark bluish case colors and patina on the breechblock, and dark brown patina on the balance. The bayonet is very good and the scabbard and frog are fine with mild storage wear including flaking on the frog. The heavily worn wood is also good and has numerous scrapes and small dents throughout, a repaired crack between the lock and front of the trigger guard, and some minor chips and slivers absent. Mechanically excellent.
