Here is the freebie DH came home with. Singer Golden Touch and Swear 640. It did clean up nice, but is missing the 5 prong cord and slide plate. My slide plate for the 401 fits it, but I don't want to rob the 401. The plastic gears seem ok, but won't know until I get it running. I was able to download a manual for the 600s and instructions for threading and bobbin winding for this model. Now to locate the parts.
