It sure is a treasure! You might be able to get a belt from your local sewing machine store if they do repairs. I was in my local store one day for something else and happened to mention that I had my great-grandma's treadle but the belt was broken. The repair guy went to his cabinet, whipped out a new belt and explained how to put it on and how to cut it to size - really easy to do. I think he charged me a couple of dollars for it. There are several good books out there that explain how to use and maintain treadles - check on-line. I got one from Clothilde. Enjoy your machine. It's beautiful.
