From The Complete Buyer's Guide to Bicycles (1973) "Chiorda bicycles were imported to the US by Portofino Inc." "The high end model was the Professional Model 1050, which is listed as $500 retail. It came with Cinelli stem (w/ allen bolt) and bars, Unica plastic saddle, Pneudan Criterium tubular tires, and all Campy components (brakes, crank set, hubs, ders.). Unfortunately the guide only identifies the cranks and hubs as Campy Record, everything else is just "Campagnolo." "Lesser models listed are the Gimondi Model 1053, listed at $200 retail with centerpull brakes (unspecified) and Pneudan tubulars; and Models 030/031, listed at $150." "Felice Gimondi won the 1965 Tour De France on Chiorda. At some point (in the 1970s?) Chiorda was acquired by Bianchi."
