BTW - don't get too worried about Singer part numbers - Singer periodically updated part numbers, even though the basic foot didn't change. I did find a few short shank blind hemmer guides for sale on eBay, along with the slant. Most cost effective way it to find it in a set, so you have to know what it looks like. Several I've seen have the attachment point to slide down over the screw instead of from the side, but it's the same other than that.
