Vintage Singer 221 / 222K Featherweight sewing machine bakelite foot pedal / speed controller. This pedal is also compatible with other older model Singers that also use a double lead cord with the same style 3 prong plug. Overall excellent vintage condition with only minor cosmetic wear to the bakelite, clean & crack free. Has been cleaned, tested & visually inspected internally. This controller still has its original bakelite plug, the wiring is copper (preferable over aluminum) and the insulation remains supple and damage free. Original rubber feet intact. Simanco part #194584. Made in USA or Canada.
