It's on my father-in-law's old Bridgestone Kabuki, he installed it some years ago. It is coupled with a wide range 5 speed freewheel and an old Tourney derailer. The ring, if I remember, was produced by some gent in CA who made them in his garage and advertised them in Popular Science or some such publication.
The label says "Durham Elliptical" and I have not found any info anywhere.
My FIL swears by it and says when he rides a bike with a normal ring, it feels out of round to him.
