Holy Smokes!
I have the same bike in blue. Glad I found your thread!!
Follow the Links below to my flickr account to see my bike set of this bike.
2nd link is to other sets of my other bikes if you have time. Thanks for posting yours now I can rest that it really is a model! Not many around as Bianchi did not import to US until 1980...although this bike has a LBS sticker from California on it. My bike is in impeccable shape except for the scratches on the top tube that somehow were not included in the set of pics sent to me. OH well...I like the bike.

My bike came with Bianchi hubs, Bianchi seat (prolly not stock), Universal 61 centerpull brakes, Campy shifters and Gran Sport front/rear derailluers. I will keep looking for more like ours.
If you decide not to build her up hollar at me! Thanks!
Take care and keep in touch!
