Definitely not a Selvino. Well, almost. I have learned never to say never. But a Bianchi Selvino had an integrated headset. The head lugs are all wrong. BB is all wrong. Fork crown, dropout treatment, lack of serial on seat cluster. All of it is atypical to Bianchi.
this era of bicycles is way out of my wheelhouse, but as i was WFW (waiting for wife) while she was shopping today, i was perusing my cell phone for bike images from that time period, and admittedly cell phone web searching without glasses can be a less than quality experience, the Selvino looked liked a possible candidate. but as was mentioned previously, that type of sport bike was not limited to Bianchi. i haven't noticed any serial numbers from viewing the seller's listing of images, so perhaps it was a small shop production. thanks for everyone's efforts...
