It was an Italian Pinerello Arco 8spd (this pic not mine-one like it) Columbus SL steel-full Campy Record w/Modalo brakeset & tubulars. It was the production version of the one-off made for Alexi Grewal who won the '76 Olympics RR in LA on it. I got it right after that.

That's a pic before I swapped frames. Same model, (SLOT1-57cm) one size bigger and in different stripe. The black 55cm one is now a back-up. Aluminum lugs/SCC carbon tubes/Easton fork. Full Campy Chorus Carbon. 10spd ti-cassette. It's a race machine so very stiff and around 17lbs. It's "old" by modern standards but a very responsive ride.

I had a Pinarello years ago, I still miss riding and it's been many years.
