It was already converted when we found it back in the 80's. I do remember sewing some on it about 15 or 20 years ago just to see if I could use a treadle. A regular belt does slip around the hand wheel nicely and for winding bobbins I can't remember, but I do have other machines that can wind them. I think our other one that I might try using is a Singer 27? ( it was made in 1898 no letters in front of the serial) with a shuttle. I just can't see winding that many spools for quilting. Just starting to renovate our old sewing machines so I can use them.
