For your consideration is this Champion 6-Lever Padlock made by Miller Lock Company of Philadelphia PA. This particular padlock dates to roughly 1900. These locks were cast from gun metal and so were stronger than other locks manufactured at that time. This is a push-key lock (not turn-key). Unfortunately we do not have a key for it. It measures 2 1/4″ diameter. It has the shorter shackle and a 9″ long chain. It is a left pin (as denoted by the little piece near the “h” in “Champion” on the front. There is a tiny “F” near the key opening. This has some dings on it, but you would too if you were 120 years old! Please see photos for more detail.
