Citoyen du monde, can you clarify your comment on the rear mech on the Carlton? Is it Gran Sport rear mech's in general that stopped at '63, or just this model? As I have a 65 bike with it's original, Gran Sport, rear mech.
FWIW, I tend to build with the closest components I can, I can't tell the difference between a lot of the Campag components anyway, and I'm not going to spend many times the price of my existing components for something that looks 99.9% the same, but has a different date stamp.
Spokesmann, lovely bike - I wish my '65 flyer still had some of it's chrome left like yours.
