Oooh, a 130. I am on a look for a cast iron zigzagger too, they don't turn up too often around here. I would keep the motor though, I think Pfaff had a slighly stronger motor than standard at the time. It should treadle well, as long as the leather belt is narrow enough for the groove in the hand wheel. I think I have seen pictures of a 130 converted to a spoked hand wheel, maybe original or maybe borrowed from a pfaff 30. I have hardly treadled at all, just a few test drives, but getting the wheel to go in the right direction can be done from under the table too.
