This is a McINTOSH no pin 6 lever push key pancake padlock. This lock was manufactured by the E. T. Fraim Lock Co. (Keystone Lock Works). One of the tough to find 6 levers. It has a Miller # of (124.2). I picked this lock and cut the key. As you can see from the shackle, it had been locked a long time. Snaps open. Thanks for looking.
