I recently picked up a Bianchi that had been powder coated, so I'm unsure of the background of it. I think it is mid 80's, since the cable routing is under the BB. There is no frt dérailleur braze on, but two water bottle bosses. This leads me to believe it is a mid range model. Here are a few pictures, if there are any Bianchi experts out there, please chime in. (I have no idea if the decals are correct for the frame)

Any info is most welcome. It has a 70mm bb, so I'm assuming it is Italian built
