Hi Ted,
Post 1981 Gran Sport info is contained in the 1982 Campy Olympic catalog that I own and is mentioned below. There are listed on pages 6-7 a Gran Sport Poad Gruppo, and a Gran Sport Touring Gruppo. Both have cotterless cranksets. What time frame are you seeking for Gran Sport info? Campy catalog #16 or earlier?
A COMPLETE set of Campy catalogues (?#1-18?) has been photocopied and is available for $85 from Velo-retro. Chuck can help you out on this...
