Of the many machines that I have here I only have one with a long shank and one with a slant shank. So I keep this in mind when ordering and new feet. I also keep in mind which machines cannot use a walking foot for this same reason. This was easier for me than finding a list of all models that had what. If I were buying a machine I would telephone the dealer for the information. I wouldn't know where to look for a list like this. Best of luck.
