Well, I am lucky enough to have a nice Singer 401-A, but I'd like a few more cams to expand the list of decorative stitches. I wonder if Vintage Singer cams are interchangeable. I found a box of accessories, including cams, for Singer 478. I tried to search on line but cannot find an answer to this question. I hope someone here can advise me. Thanks bunches.
