I just went and checked. I have a Singer Professional buttonholer for vertical needle (low shank) zigzag sewing machines. I also have both an early and late model Professional buttonholer for slant needle zigzag machines. I like the rounded housing on the early model better. Looks like they are for zigzag only, not straight stitch machines. I don't know if they were available for other machines. I'm guessing not. I see them occasionally in the thrift stores around here.
I'll keep my eyes open. If I see another low shank one I'll grab it for you.
