This is Cleo. She is a Singer 127 Sphinx Treadle Machine from 1916 (SN G4994196). She has not been altered with a motor. I purchased her off of Craig's List where the seller was selling her as an antique piece of furniture. He thoughts I was nuts when I started gingerly checking moving parts. "You are not planning to really use it are you?!" With TLC and a new belt she smoothly sews beautifully.
