I have several old sewing machines, mostly Singers. I have used them, but now don't have the room to have them set up. Am currently trying to get a new or used motor for the one I learned to sew on; it was my mother's. They are good for sewing on leather and other heavy duty fabrics, as they don't bog down. The new computerized ones overload the motor and shut down on you. I do have a White treadle that I have used but currently don't. One of these days when I have time to fiddle I will get it out.
