I sat down with the box of attachments I also got along with the 3 machines. Some fit my current, "modern" Kenmore and I think the rest of them are high shank and will fit the new "vintage" Kenmore I just acquired. It was so fun to go through them and see what they do...with my current machine. The ruffler was fun, the tucker, the rolled hem, the binder. I have a vintage Singer instruction booklet that I used to identify all of the gadgets and how they work. So, now I have rotary attachments for the circular shank, others for the square shank kenmore types. Fun.
