Fizeos, IF you like to treadle, then the treadle irons can be cleaned up. They look pretty! You can make another top for the irons and drop another machine in, like a Singer. It looks like the Pfaff treadle petal is set off to the left so that it sits under the sewing needle area and not the center of the machine. Singer treadles are centered under the center of the machine. Some folks prefer the treadle to be centered to the left as this one is, or like the Whites. Pretty treadle irons that needs a good cleaning, Enjoy!
