I love all of my antique Singers-they sew straight seams, are easy to maintain and are so pretty! I have a treadle (if we are ever without electricity, I'm still in business!) a 15-91 (good heavy-duty machine, will sew threw almost anything) and 2 featherweights-a 1949 and a 1951. The centennial model is just a show-piece-but I love her because we are the same age!
