66cm Calfee

Just stumbled on this and while I don't have any first hand experience, I do know a good friend who had one, was a true believer and from when I went to NAHBS in Sacromento 2017 where his booth was busy the whole time I was there.
He was in high demand and great to talk to, has plenty of fans and plenty of business, very well respected as a pioneer and innovator for a long time now.
Absolutely the real deal as far as I can tell.
