My 201 might have been a treadle, but was converted to electrical pretty early on. It's a 201K, which means it was made at the Kilbowie factory in Scotland. The irons are gone, but it has the spoked hand wheel and is in a one drawer fold-alway cabinet that probably had the treadle parts at one point. I have seen the later 201K23 as treadle too, but those are few and far between. I have once seen the hand crank version, and have seen pictures of a treadle on the web. most are with motor. I'm in Norway and the 201K sometimes turn up in treadle cabinets, most by far are electric. I guess a few UK made 201s have found their way to the US. In the least, they have been spotted in real life outside of French tapestry.
You are lucky having lots of 201-2s with the potted motor in the US, but they don't convert easily to treadle. An alternative could be to track down a Singer 15, a Pfaff 30 or Husqvarna CB; they have the reverse stitch lever hand came as treadles too.
