I honestly don't ever remember seeing them before, anywhere. The ones that came with the cmp where the 1st of these type I have ever seen.
Could be wrong though. If Robart did make at one time, problems or no demand, would have made them dodo bird.
A Google search for Robart Horny Hinge comes up with lots of hits but I'll be damned If I can find a picture of one. I can't remember where I saw them now. The point is moot if they aren't produced anymore. [
