If you go to
http://www.april1930s.com/ she sells anything FW including attachments, cases, needles and bobbins as well as repair of original foot controller (be sure to check it because the wiring in old ones can come loose and be a fire hazard and the bakelite plug can be cracked). They can repair or replce your foot pedal. I have bought several things from them and she and her husband are good to work with and make exchanges with no fuss. She also sells copies of the original owner's manuals as well as the service manual, which is a real help, plus belts, lights and even replacement motors if you ever need one. She also sells the oil and motor lubricant.
