Thank you so much Joe for the information and the welcome! You've solved in just a few minutes a mystery that I have been searching for the answer to for days.
Are you saying it was probably exclusively a treadle and was electrified later? That makes the most sense to me since the motor is not a Singer motor, although it could have originally been electrified and the motor replaced at a later date. I would love to find a treadle base for it, I'll be scouring my local CL trying to find something.
I'm busy trying to help it as much as I can, but I need more information before I move forward. I'd hate to do any more harm to it than need be. I'm really worried about touching that finish and the decal with anything until I'm sure it's the right thing to use.
The electrical parts are scary, I am thinking I may try to find another motor for it if I decide to go that way.
Thanks again, I really appreciate it!
