The "camel toe", attachments look like the ones for my mother's White Rotary, 1921 treadle machine. One of the bobbins,, with the slightly rounded top, is a class 66 and will work on your 201, The other bobbin is for a White or Kenmore, as they can use the same bobbin. The other attachments look like the ones you see in the blue velvet boxes. Sorry they won't fit a 201. The 201 is an excellent machine. I have two and love them. They will last into the next millenium, with care.
