I have an old sewing machine cabinet that does not have a sewing machine in it. I know this is a long shot but hoping someone has one that will work with it. I have enclosed pics of how machine hooks up to cabinet . Cabinet opening is 16 1/2" x7".  I believe an old style touch and sew or singer Rocketeer model, or slant o matic would fit. Holes in back of machine to hook up to cabinet is 9 1/2" apart.
