Mine is clamp on front mech and originally had Super Record groupset. The sticker below the lug on the down tube is "Campione Olimpico, Campione d'Italia 1984" apart from the usual red one incorporated in the Pinarello decal on the seat tube (about the Italian and European Championships 1981).
Far as I know these stickers are on the treviso right up until the early nineties-I had a Treviso I sold early last year (with full 7400 Dura Ace and braze on so guessing '86) and weirdly enough all the decals came off on just one side, leaving the other virtually mint? I could only figure it was the side that was nearest my garage wall that was getting damp or something... I've seen replacement sets on French eBay.
