The main two reasons I think it's a non-Singer refurb are these. The lack of motor boss and the non-Singer looking motor, and the serial number has been painted over too. I have a factory crinkle machine from 1938. It's got updates to it ( the more modern bobbin winder and the later stitch regulator) and the serial number is clear and unpainted. I'm posting my front view pic again just for comparison purposes. If money wasn't so tight I'd go for that one GW just see what it really is. Joe
