Another brava thread! awesome!
anyways, yours does look to be an early model as with what the other posters said, but that serial number conflicts with the 'italian made' sticker that appears to be on the bike, as that number would be an asian made bianchi. The italian ones are a bit more cryptic throwing in the odd letter and '.' character.
you included some awesome pictures that really do some good ID work of the bike, kudos to you thats better than most ppl here - including myself!
wow, i just noticed this is a ressurected old post!
oh well, my brava.
Bianchigirll, can you make a scan of the 87-88 catalog?!
