OK, I didn't post this question nilly-willy.
During one of my volunteering shifts at Bike Farm here in Portland (I swear, between here and the Community Cycling Center on Alberta, Bike-Recyclery gets 90% of the inventory) there was a conversation on how house-made Colnago panto parts stopped being Cinelli and started exclusively 3TTT.
If you have access to the colnago spectrum (steel frames people) I think post 1983 everything was 3TTT and no Cinelli to be found. Of course we are talking stems and bars.
One of the old guys who is a bit of a Cliff Klaven spouted about some argument they had. I've googled, nada.
Thought I'd bring it up here.
