I have a 1934 99K, it came with motor and lights, and the small solid hand wheel. When I got it, it had two cylinder shaped capacitors (not sure if it's the correct term in all cases), just a bit larger than an AA battery, a wire comming out of each side of them. I guess they can have been a later additon, and I always thought they looked a bit odd. Later I have realized it was the regular way about it back then. They were wired on to the electrical socket, just under the hand wheel.
My machine blew up with a bang and it was caused by these cylinder shaped thing. There was literally a bang from the machine, a fuse blew and the lights went out, but no visible signs of an explotion. I handed it in for repair and rewiring, and it came back with all original parts (motor and knee cotroller) except for the old cloth covered wiring, the capacitors were just removed, not replaced. I was afraid the repair guy would return the machine with a note saying it wasn't repairable, but it came back in working codition with a stitch sample under the presser foot.
The old bakelite pedals work fine, as well as the metal versions, it's not a must to replace them, but they can need need a good cleaning and sorting out. I know the new pedals should in theory be better, but for some reason it isn't always the case. You can end up with just the same speed issues as an old one that needs adjusting.
