The Winchester factory 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. Manufactured in 1873, this Third Model has the correct 27 inch round barrel with the magazine tube that stops about 2 3/4 inches from the muzzle allowing this rifle to have a full 17 round capacity. The top of the barrel is marked with the two line address/King's improvement patent dates and there is a small "J" on top at the breech. It has the third pattern receiver with the block 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 a brass carbine buttplate with cleaning rod compartment, (not included). Complete with an original 15 1/2 inch socket bayonet.

Fair. The barrel, barrel bands and magazine tube have a dark brown patina overall with moderate pitting on balance of the barrel and magazine tube. The sharp edge brass receiver and buttplate have a dark age patina. The wood has been sanded, and oiled, and remains good with a few minor age cracks in the stock and overall some minor dings and handling marks. The markings are clear. The action is very good. The bayonet is good with a dark brown patina and some pitting on the blade.
