I can post some pics, but I'm sure it's an 87. It had a sticker on it that said 86-87 on it as well as the made in Italy sticker. It also had a sticker confirming it is in fact Bianchi Formula 2 Columbus steel. Although I took all these stickers off the bike. I know that some may hate me for removing them but they were tattered, faded, torn, and somewhat unreadable. I did leave one columbus sticker on the fork that was in good condition.

The crank, brakes and derailleurs were as you stated, but I replaced the brakes with Campagnolo Centaur dual pivot brakes.
