you know the only Bianchi I can find any info on that has Vittoria in the name,
uses a Vittoria Margherita derailleur, that would date it back in the late 30's
early 40's. They had teeth on the rear dropouts which makes it easy to
identify.
I agree that the aero seatpost, 6 speed freewheel are 80's items but
they may have been add ons/upgrades to an old frame.
Post pics if you can.
