Charles, Dale & List Just received a response for the owner of the CASATI He says Columbus MAX is ovalized (period 1995) Wayne ( Sleepless in Toronto) Jolly, Ontario, Canada
Here are some more details-
The bike is practically new since I only rode it a few times. It was built from the ground up back in '95. w/ all campy c-record components. I don't know anything about the Bianchi you mentioned, but the Frame on it is a Columbus Max Frame, which slightly ovalized at the seat tube and down tube to provide extra strenght. It is a great comfortable riding bike with just the right amount of flex and stiffness to it. It has Mavic Open 4 CD rims and Pariba clinchers.
