Here are a couple of Sphinx pictures, she was born about 1913. Right now she is at the doctor's (DH basement workshop) getting her greased and tuned. May be ready in a day or two. I will need a new belt, I think. And what would I use to polish the black iron stand?

Very nice, I have the reproduction model of your machine. I don't sew with it, I have it on a treadle stand in the living room. The machine was given to me by my Aunt Jo.
