So lets hold off on the swap to a treadle until I have some facts in front of me.

I have seen a potted 201 converted. All that was done is remove the motor and motor housing and replace the bobbin winder with a Japanese class 15 donor. I vaguely remember hearing that the potted 201 machines were made 2 different ways, so some could have a motorectomy and work, and some could not. I just cant remember why!!
