I have an early '80's Casati frame. It is 54 ctc. Top tube is 54.5 ctc. Rear brake cable is routed through the top tube. More interestingly, the gear cables are internally routed as well. There are bosses for standard Campagnolo downtube levers, but the cables are immediately routed through holes in the downtube. The front deralleur cable emerges from a hole at the base of the seat tube. The rear derailleur cable comes out of the chainstay right at the dropout.
Paint is a bright, but somewhat sunfaded red. The model appears to be a Perfection, at least that is what the chainstay decals say. Maybe that is just Casati's opinion of their framebuilding skills. There is a rear-facing decal on the seat tube, that I like because it suggests that the rider is confident that someone will be behind him.
Included is a chrome Casati fork of later vintage than the frame. I was hit by a car while riding, and the original fork was bent. My LBS, Continental Bike Shop in Hazel Park, MI, checked the alignment of the frame, and they said it was straight.
Also included are a Campagnolo NR bottom bracket, and one bolt SR seatpost.

In the event of multiple offers (I should be so lucky) I will do some kind of coin-flip-random-number thing to pick the winner.
