Cathy, Does yours have a belt to run the bobbin winder? If my perspective is accurate a dedicated belt or treadle belt is needed to run the bobbin winder.

Ron,
Good eye! There is a spring in a loop shape that stretches from the motor pulley to the bobbin winder.
I'll post a picture when I get home tonight.

It does look like a Rube Goldberg type idea. However, in it's simplicity it does work very well
The circular spring for bobbin winding is original. Over the years I have had several of these motors
come with springs. Here it is shown in the manual.

I found this blog and it explained the odd spring in the carry case under the machine. The picture was helpful. I have been told mine is a S40 model made by National. I need to learn how to thread it.
