I love my Singer treadles. I have 3 Singer treadle cabinets and 6 machines that I swap out. A 1914 Singer 115,1916 Singer red eye 66-1,1921 Singer 66-1 red eye,1936 Singer 201-K hand crank/treadle, 1949 Singer 15-90(motorectomy preformed),1968 Singer 237(motorectomy preformed) and a 1955 Pfaff 60 treadle.
I make most of my quilt tops with the treadles, currently using the 201,115 and Pfaff to make quilt tops.
