Hello - I am picking up a 15K88 1951 Centennial Treadle - the lady just wants to get rid of it because she bought it 10 years ago for decoration. I had no idea they made treadles up to that year. Would this be a machine that perhaps was treadled after? I was thinking of placing it in a box and converting to hand crank with parts from sew classic. Will post a pic tonight, after I pick it up.
