Well, folks, the bug got me too!
My BFF and I went shopping yesterday and I found a Singer treadle machine that seems to be in fairly good shape. Needs a belt and some cleaning, but moves easily top and bottom.
According to the Singer website it is a model 15k manufactured in Scotland in December 1947.
My phone doesn't seem to be saving my pictures. It's still in the bed of my truck awaiting being moved to my sewing room so the pictures were kind of wonky anyway.
Any further info on this machine would be most welcome!
