Information for Mod. 66 carbine, designed by Winchester, USA 1866.:
he original Winchester rifle- the Winchester Model 1866- was famous for its rugged construction and lever-action mechanism that allowed the rifleman to fire a number of shots before having to reload: hence the term, "repeating rifle." Nelson King’s new improved patent remedied flaws in the Henry rifle by incorporating a loading gate on the side of the frame and integrating a round sealed magazine which was covered by a fore stock. Originally chambered in the rimfire .44 Henry, the Model 1866 was nicknamed the "Yellow Boy" because of its "brass" receiver (actually a bronze alloy called gunmetal).
