Manufactured in 1870. The carbine has the distinctive brass receiver, round barrel, full length magazine, barrel band with integral front sight, two leaf rear sight, saddle ring and staple on the left side of the frame, and walnut stock with crescent brass buttplate with compartment. The bolt retains its original rimfire firing pin. The top of the barrel is stamped with the two-line Winchester address/King's improvement patent dates ahead of the rear sight. The lower tang has the serial numbers stamped behind the trigger. The '66 secured Winchester's place in the annals of the West and launched a long line of successful Winchester lever actions that remain popular to this day and still retain the basic form of the '66. It was one of the earliest and most widely used repeating rifles in the American West and saw use in conflicts over land, gold, and other resources on the frontier in the second half of the 19th century in the hands of settlers, Native Americans, outlaws, lawmen, and hunters.
