Hi All, Can anybody tell me if Singer 111W153 parts are interchangeable with a 29k? I purchased a Singer 29k some years ago and it came with a box of 111W153 parts, all still packed in cosmoline and sealed in boxes. I hadn't really had a chance to take a hard look at the boxes until now and they are marked for the 111W153. If these aren't interchangeable, which I assume they are not, anybody interested? Thanks Vicki
