The cups with a triangle on them were part of the Triomphe gruppo (manufactured '84-'86). However, I remember that some of the NOS Triomphe bbs I had didn't have it. So it may have started some time after the initial introduction of Triomphe. I think it is coincidence that the "T" in the triangle should be construed as standing for Triomphe. I mean, why would Campy put a special stamp on their lowest line bb cup to signify a model, when they have never done it before on any of their past and present (at the time) lines of bbs. So my guess is it stands for something else, but I don't know what. I can't remember for sure, but those same triangle stamped cups may have been used for the first years of Athena as well.
I don't understand you last question, could you rephrase?
