The 401G was a trash day rescue a few years ago - I had to learn the hard way not to use liquid wrench, anything you spray in... WD40, 3in1 oil - it was dirty, rusty in places and locked up tight - I never really dreamed it would sew or was so special. I worked on that one for two years before I got everything working right. It still could use some more clean up. The motor is cracked. Speaking of motor and electric. The G models take the same foot control & cord as the Singer Featherweight - one plug two cords. The 401A takes two cords with two plugs.
