Uberti Yellow Boy 1866

Given the historic breakthroughs achieved with the Henry rifle, Winchester improved on its design to make it even more useful on both the range and the battlefield. In 1866, they introduced Nelson King's patented spring-steel loading gate, as well as a wood forend for added comfort. These changes led to the creation of  the "Yellowboy," the earliest version of the quintessential cowboy rifle whose lines and basic functioning survive to this day.
