Manufactured c. 1875-1881 and in the configuration of the No. 5-1/2 Montana configuration only produced in small numbers c. 1882-1884. Only 14 or so original No. 5 ½ Montana rifles are known today. The barrel and frame have matching serial numbers. The barrel is also marked "45-100" on top at the breech.

Good with refinished barrel, light original case colors, absent rear sight elevator, mild overall wear, spliced forearm, and some cracks in the wood. Mechanically fine.
