I have listed two early Campagnolo Gran Sport bar end shifters. I do not not think they are first generation but am fairly certain they date from 1952 or 3. They are listed as #'s 180037880736 and 180038108728 . If anyone is interested and has questions please feel free to contact me off list. Thanks for looking. Edward Albert Chappaqus, N.Y., U.S.A
