Thanks everyone for all your help and suggestions.
Here are some pictures of the motor and foot pedal for the machine. My thoughts are that the motor is original, or from another machine that was similar, but that the foot pedal is an addition since it is brown, not black and says Singer on it. The machine has a serial number 103171 embedded in the front of the base and the numbers 514 embeded in the bottom but no other markings of any kind. Someone put a label on it that says "Distributed by the Chilliwack Sewing Machine(?) Supply" with part of an address. There is a Chilliwack in British Columbia in Canada with a Yale Road so looks like it was distributed in Canada.
