Color me jealous on your find! I have bought two bargain Pfaff 130 machines and taken them to the OSMG, but he hasn't been able to make one working machine out of them yet.
That cabinet is really cool too. I like a lot of Pfaff's cabinets.
If you have never tried a knee controller before, you should definitely try it on this machine before you convert it to a foot pedal. I have one machine with a knee bar (Singer 503A) and I get much better control of speed, stop, and start with the knee bar than I do with foot pedals. You may find you prefer the knee controller.
Have fun with your new toy.
