I suspect perhaps the shifters were upgraded, does this have a shimano cassette or freewheel? a shimano cassette or freewheel may have been added to make it shift better. are the cranks Ofmega Quattro aswell?
again IMHO judging by the style of Bianchi decals, the silver Columbus CroMor, decal and the Quattro this is a '89 or '90 Campione De Italia
a Mondiale from that era would have a frame of either Bianchi Special tubing, SL or SLX.
