I need to locate some parts for my old Seamstress sewing machine. It has been tentatively identified as an Expert B.T. Vibrator, 3/4 size. The machine is dismantled at the moment for cleaning and oiling. I need to find the front slide plate, a stitch length thumb screw, an Automatic Spooler friction wheel (rubber or fabric) for the bobbin winder, another bobbin or two would be great (little metal ones that look like a stick with a disc on either end), and I have heard tell of a cloth guide and thumb screw. Advice on something to clean old grime from the body without totally removing what is left of the decals would be very appreciated, as well as a solution to rust on the bed.
