MimiBug123,
I have 4 functioning treadles, two of them Singer red eyes. One of them had been electrified sometime eons ago and I put it back to a treadle. Lots of work but it turned out great.
One is a Franklin 1911 in a parlor cabinet and the fourth is a Singer 9w-7 in a substitute cabinet until it's original cabinet repair is finished.
Would I electrify any of them? Noooooooooooo. There is something unique about each machine even if they are the same model.
Would I paint one? Yes, but if and only if the original paint was in horrid condition like my New Home Model AB. Eventually I may just make it look nice again.
Joe
