Quoted from Palooka61:
Another friendly Palooka owner confirmed that my score motor is indeed running the wrong way around.
Cool. You won't see this often. These motors are usually riveted together with long brass (?) rivets in the corners of the frame. Your rivets appear to be missing. Is the the case? Can you pull the two halves of the frame apart (just a little for now)?
If the frames can be separated it may be that someone has taken the motor apart at some point. That might explain why your motor is turning in the wrong direction. If the motor was taken apart and reassembled with the coil and steel laminations installed backwards that would cause your motor to run backwards.
These are called Shaded Pole Induction Motors because they use Shading Coils that force the motor to always start in the same direction. The Shading Coils are copper coils around the laminations as shown here:
Without the Shading Coils this AC motor could start running in either direction. If your motor was reassembled incorrectly the Shading Coils might be in the wrong orientation and if so would force your motor to always run in the wrong direction.
Your 50 Hz motor was probably built for use in Europe. It might work ok on 60 Hz although everything will run 20 percent faster.
