I repaired my old kitchen clock, manufactured in October 1948. I got a new old stock coil and put it in. Oiled judiciously. Now it runs very quietly and smoothly. But I wonder if it's running too hot on its 12 hour first run after the repair. When I touch my knuckle to the metal over the new coil, I can hold it there about seven seconds before it's too hot for my skin. It was the identical part number from the original. You can see in this picture right by the two screws over the coil and the left part of the motor, where I placed my knuckle, and this is the place it is the most hot.
