the 201 is a pain! Enough so I don't think I could get DH to take one apart to take pictures. He did these for me earlier this year when we were helping someone on another board figure out what was missing under her machine. She had no shuttle body - so the bobbin case kept falling out on her. Easy fix - then she realized her bobbin winder was gone. A good example of someone using a machine for a few parts, then "donating" what was left to Goodwill.
