Campagnolo's 1991 catalog contains much of interest to fans of the stuff from Vicenza. In 1991, Campagnolo still offered a full line of MTB components (later dropped in the face of competition and better parts from Shimano), as well as two separate tandem lines--one for road use, the other for off-road. The names of the gruppos include the familiar (Record, Chorus, etc.) and the obscure (ever heard of Themis and Xenon?).
Also included in the '91 catalog was one of the few appearances of the Record gruppo in the unusual "Century" finish--a dark grey anodized finish that was offered for only two to three years. Only about 300-500 sets of Century-finished Record gruppos were shipped to the United States, making it among the rarest of gruppos.
