I don't know if there is a real market for a Singer 66. I have one I bought in Waco, Texas for $25.00 40 years ago to teach my two daughters ages 8 and 9 to sew. It was the first "old" machine I bought. Since the girls learned to sew, I have taught a ton of girl scouts how to sew on this machine. It was not a treadle. For many many years it was my backup sewing machine. I didn
t have a featherweight or any other lug-able for quilt retreats so it was mine. It is currently set up in my sewing room about one a year I clean it up and oil it. I have never had a major problem with it since I bought it. I can't say that for my newer plastic machines. It is not for sale ever....I may consider adoption by a "qualified person" but then I have 4 grand daughters who are reaching the age to learn to sew....maybe "66" is back in business soon. This machine will out sive almost every one!!!
