nice looking bike. someone put alot of money onto that old frame. is that an aluminum fork or just an odd crowned steel? I agree on the seat post it likely is 26.4. (if I ever find that seat tube guage, I am going to buy it then rent it out LOL) I see a red Classica in '83 *dark* + '84 *Cardinal* for 300 I don't think you did too bad, I guess the builder did not realize what kind of frame it was.
taking a third look at the pics something about that HS and stemm bother me are the spacers under the stem for looks?
OH "E" yes Bianchis did come with stem shifters. in the early to mid '80 most of the lewer end bikes had them and the Classica was one of them
