Thanks, Rodney. I looked on e-bay and the only "match" that came up was for a high shank, like for a Necchi. I have a couple of versions of those, but I was curious about one for a super high shank for the old Kenmores. I thought they didn't exist so was wondering if I was wrong. I couldn't tell which type was pictured in the OP, but it's likely a low shank which was also common on older Kenmores....but that screw does look like the type on the super high shank.
