FROM WIKIPEDIA

A Winchester rifle is any of a series of lever-action repeating rifles manufactured by the Winchester Repeating Arms Company. Developed from the 1860 Henry rifle, Winchester rifles were among the earliest repeaters. The Model 1873 was particularly successful, being marketed by the manufacturer as "The Gun That Won the West".
