The old Singer treadles are so reliable. They my not do the fancy stuff that the new machines do but they can sew through just about anything that will fit under the foot. I use mine for sewing up blue jean hems, double upholstery fabric purse handles, cammo tent fabric etc. Some people can even use theirs to FMQ quilt on. I don't know how they do it but way-to-go treadlers. I can also sew when the power goes out and get great exercise!
