Eric, There are others more qualified (Marc) to reply but I'll relate what I know. I don't think it was only one company as much as a style of tricking out standard Campy parts. I have seen different styles and treatments mostly all centered around Colnago's. Brake calipers and cranks got most of the attention in the milling, polishing and reprofiling. I have a 30th Anniversary 1984 Colnago Master Equilaterial in brutal red...CHROME head lugs, bottom-bracket, seat-cluster, brake-bridge, drop-outs ect. The gruppo is a Colnago 30th Anniversary Campy Super Record. The cranks are reprofiled, polished and pantographed as are the brake calipers. The brake and shift levers are polished and engraved as well....In fact everything seems engraved.
"Nothing exceeds like excess!" I ride this bike several times a year....It hangs over my desk in my home office and recently took a 2nd place at a Concours in Huntington Beach, CA. It's a blast to ride but I have a few other Colnagos to ride as well.
