Anybody ever seen a 1-point balanced head mower?

One time I came across a picture of an IH balanced head mower (i.e. a 100/110/120/1100/1200/1300) with a one-point fast hitch attachment.

I'm betting it's extremely rare, but has anyone else come across it? My google-fu is failing me on this one.

I have seen one at an auction sell for $50 that was in really nice shape. Not really having much interest in those type mowers and wanting to deal with loading it and risk getting hurt, I didn't buy it. Wish I would have!
