Champion Push Key Lever Padlocks

Three of my Champion push key lever padlocks. These were manufactured by the Miller Lock Company, USA. The two 4 lever padlocks actually have 5 levers - these locks were never made with 4 levers. The diameter of the padlocks are (from left to right) 1¾ inches, 2 inches, and 2¼ inches. The padlocks are made from Gunmetal/Bronze. Brass was not used as a material until the introduction of the "Empire" brand as a cheaper alternative.
