I have a vintage Necchi Supernova sewing machine that requires a screw-on high shank walking foot. I've been searching everywhere for one and haven't been able to locate one that is compatible with the supernova. I'm wondering if any walking foot, if it is high shank would work. Anyone?

Most of the genertic ones are interchangable. The worst thing that would happen is that you have to return it. Go for it!
