I hate to change the subject, but I was cruising through ebay sewing machine attachments last night and came across an ad for what purported to be "Featherweight" attachments. Part of the group shown in this seller's photo were black cams (appear to be cams for a Singer 328K). I had to laugh! Obviously this seller knows nothing about, to say the least, Featherweight cams! LOL
