The Winchester Model 1885 was Winchester's first firearm capable of firing powerful big game cartridges and is based on designs patented by John Moses Browning in 1879. The .45-125 Winchester Express cartridge was introduced in 1886 and only available by special order and discontinued after only a few years making rifles like this one chambered for this long express cartridge true rarities. This early rifle from 1887 has a beaded blade front sight, the two-line address ahead of the three-leaf express rear sight, "45 EX." on top of the barrel at the breech, "4" on the bottom of the barrel ahead of the forearm, "11" under the forearm, "45 EX 7" on the bottom at the breech, a period modified Vernier tang peep sight on the upper tang, casehardened frame, patent marking and script serial number on the lower tang, and smooth walnut forearm with contrasting insert in the tip and straight wrist stock with steel shotgun buttplate.
