The Cologne Ball Vibrator . . . not what you think!

I came across this interesting old motor . . from the early 20th Century, made for medical purposes.
This is the video of a guy restoring this rare and antique electric motor.
Enjoy, and tell us what you think . . .
PS, watch it in half speed if you want normal playback speed.
