I bought a treadle just like it a couple of weeks ago and I downloaded a manual off the internet. I also paid $100 for mine but it needed a belt and the presser foot and tension were seized so I took it to my machine repair man and it cost me $170 to get it all fixed but I think it was worth it. I've even sewed a couple of blocks on it. Wooks like a dream. The manual came in handy when I had to wind a bobbin. I couldn't remember how to do it. yours is probably similiar to mine. Go to Singer.com and check for a manual.
