Manufactured in 1870. Winchester actually termed these Model 1866's as "Infantry Rifles" because the term "Musket" evoked visions of the unwieldy long barrel, large bore rifles that were produced during the Civil war era. This Third Model has the correct 27 inch round barrel with the shorter factory magazine tube, that still carried a full 17 round capacity. The top of the barrel is marked with the two line Winchester address/King's improvement patent dates. It has the third pattern receiver with the block numeral serial number located on the lower tang directly behind the trigger. Standard musket folding ladder style rear sight with a fixed front post sight. Mounted with a smooth walnut 3/4 length forearm and straight grip stock with sling swivels and a brass carbine buttplate with cleaning rod compartment, (cleaning rod not included).

Very good. The barrel and magazine have a smooth brown patina with some minor oxidation on the breech end. The brass has an aged patina. The wood is fine with a few minor dents, dings and handling marks. The barrel address is clear. The action is fine.
