I took the dressmaker machine to be repaired and the repair man said that it was made by Riccar. He also said that he had never seen a bobbin winder like that and doubted if he could find one to fix the machine. He went on to say that I needed the cams to do any thing besides straight stitch. My daughter found no cams with this machne. I guess it is back to the dumpster for this poor old lady. Kathie S.
