I need some help with an identification of a Raleigh Gran Sport that I had given to me. The serial number, stamped on the BB is RA21437. In looking at the jaysmarine website,it looks like it might be a 1962, although those era bikes were stamped near the seatlug. The bike has a Campy groupset with the RD stamped Campagnolo Gran Sport. I'll try to attach some photo's later. Any help on the serial #/year is greatly appreciated.
