I have Helen, my grandmothers 201-3 from 1951-2 and some years ago I had to replace wires, went to singer store, but the set of wires and with a screwdrive it took about 10-15 minutes. IF you find motor doesn't work, then replace, but why if it works fine, just get the new wires, put them on and let us know how she goes. Great machines.
