The Model 1873 was the first repeating rifle made in this country for the .22 rimfire cartridge and was the first rifle made by Winchester for a center-fire cartridge. The receivers were made originally of forged iron, later changed to steel. Standard barrel lengths were 20", 24", and 30", but other barrel lengths were available on special order.
The Model 1873 was an eminently successful rifle and especially on the frontier. It did much to establish the prestige of the Winchester firm and remained in production until 1919.
