I have several old sewing machines, a couple are Singer's. I have the one I learned to sew on as a child. I believe my mother got it when my oldest brother was a baby, which would have been around 1936. It needs a new motor. My son tried to fix it but the copper winding inside the motor is all melted. My mother used to run the vacuum over the cord, and other neat little things, the cord is a mess. But the machine looks a lot like yours. I also have a handcrank Singer in a beautiful wood case. According to the Singer site it is the first true portable sewing machine ever made. It works, but I haven't used it yet.
