The introduction date and when the pedals were first made would be more than a couple of years actually. Here's the note from the Timeline: "Typically the development of Campagnolo parts was carried out with the help of professional road and track riders on teams sponsored by Campagnolo. For this reason, Campagnolo parts were in use one or more years before they were ever offered for sale to the public. Campagnolo parts could appear in stores or on bikes before ever appearing in a catalog or, on the other hand, were not necessarily available at the time a catalog was issued. The catalogs were typically printed for the trade shows which occurred late in the year (the Milan bicycle trade show was held biannually, odd numbered years). Therefore dates established by a part's appearance in a catalog are, for the most part, approximate."

For Tullio Campagnolo this would be substituting different materials for his existing designs. His steel headset and his aluminum headset have the same form and dimension. His steel bottom bracket and his titanium bottom bracket take the same form. It is doubtful that Tullio would need to be informed by Pino Moroni about the substitution of titanium for steel in his components. And Ernesto Colnago did not make components so it's doubtful if he would be telling Tullio how to make components either. Campagnolo used OMAS to manufacture the titanium parts for the Super Record group.
