My Bianchi Campione d'Italia is a 1982 model, made in late 1981, also with butted main tubes (mine are Columbus, yours would presumably be comparable) and Falck CrMo forks and stays. It's a notch below the high-end models ("the good stuff"), but significantly above the various base models. Yours is a few years newer, so my original component list might not help.
I do have spare Campag. and Modolo (OEM ca. 1980) sidepull brake calipers that should fit your frame, if you are interested in either one. (I switched to Shimano dual pivot for significantly superior braking performance.)
