Manufactured in 1868. These Model 1866 carbines were highly valued in the American West, both for their durability and their mobile firepower. Their rate of fire was nearly unmatched when compared to other long guns of the period. The 1866 is often cited as one of the "guns that won the west" and was carried throughout the Western Frontier by settlers, Native Americans, outlaws, lawmen, cowboys, and ranchers. Many of the Model 1866s were later converted to centerfire to utilize more advanced cartridges; however, this example remains in its original rimfire configuration. This example has the desirable, early production, two-line Henry and King's patent barrel address. There is an "A" marked on the lower tang. The matching serial number "18261" is marked on the left of the lower tang, in the stock inlet, and inside the buttplate ("8261"). It is fitted with a blade front sight, integral to the front barrel band, a two-leaf rear sight, and a saddle ring mounted on the left of the receiver. It is mounted with a smooth forearm and straight grip stock with a trapdoor crescent buttplate.

Very good, the iron showing mostly a smooth dark, untouched brown patina with some scattered light surface pitting/spotting and the fine brass showing an attractively aged patina. The wood is good with some rough grain texture on the forearm and some scattered minor handling marks. Mechanically functions if the trigger is manually reset; otherwise, the hammer does not hold at full cock. This "Yellow Boy" Winchester 1866 saddle ring carbine really has the "Old West" look!
