What's up with the serial numbers? I have what I believe to be a '93. It is a 59cm Reparto Corse. Serial # 59C392. Columbus EL over size with internal cable routing, ovalized downtube at the bottom bracket, drop outs are stamped "Bianchi". I am looking forward to building it up, but I am short on the cash to do so. I am not sure what the componets were originally, but it does have a Shimano bottom bracket installed.
