After some further research I have narrowed this down, I believe, to a 1987 or 1988 model based on a few things. The first would be some of the 105 components were only available for these years, the second is a "campione olympico et campione d'italia 1984" decal on the top of the down tube. These are referring to Pinarello's 1984 Olympic gold and Giro d'Italia vicorties which were, correct me if i'm wrong, their last major victories until until 1989. If anyone can find the catalogs from 87-88 that would be great. I am having no luck so far.
