Talking about that pedal, I have some Singer interoffice memos talking about that pedal. The engineers were talking about you put your whole foot on the pedal and use your heel to operate the machine. It was designed to keep your foot from getting fatigued from long periods of use. That is why the foot control is so big.
Some useless Singer trivia for you!
