I saw on line that the 401G can be hooked up to a treadle because of the openings in the base - it would need a different balance wheel though - there is info on line:

I would LOVE LOVE LOVE to treadle mine - that would be the BOMB!! I wonder where to get a balance wheel like that? Could one be made?

I've taken the grooved balance wheels off other machine and compared to the 401 - none interchange - I wonder if it can be cut and welded or something to get one. Any metal workers?
