I recently found myself in possession of a 1953 Singer 201. The power cord was damaged and I couldn't get power to the machine. I had another Singer of the same year with a good power cord and it worked to turn on and test the 201. After a few stitches smoke started billowing out from the motor. I would like to know if it is worth getting repaired or should I sell it as a "decoration only" or "parts only"?
