Nancy, a 401G is set up to be a treadle machine from the factory. I have a 401G and a 411G I posted pics on the photo gallery eons ago but here is the 401g for now. I think somewhere on here I posted pics to show the difference between the 401a and 401g. If I get my act together, I can post a thread by itself some time. I have a lot going on here until next week... I hope.
