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.
