I would love to find cams (seam formers) for my Husqvarna Viking 21. These are not the same cams as those that fit on the later Vikings which are fairly easy to find. I have two "C" cams but would love to get an "A", "B", "D" and "E" or any of the variations on these such as "A1", "A2", etc. I can also use an extra bobbin case, hook, bobbins, etc. I had a really tough time getting the belts at a reasonable price but finally found a repair shop in PA that had some. I know that there are not as many vintage Viking owners here on the QB but if you come across any of these parts it would be wonderful! Thanks!
