I, also, have a late sixties Carlton, a Grand Prix, that bears the Raleigh head badge. These were imported to the North Americian market during the dramatically increased demand for bikes during the "Bike Boom" years (1968 to about 1973). Raleigh had bought Carlton out and rebadged bikes as Raleighs. Have a look at my current project, a nothing special road bike but I am a sucker for chrome plated head tube lugs...




I plan to dump the Simplex transmission...



For a Campagnolo Velox group that I have tucked away...



The other departure from stock component issue will be the saddle. I have two BIM suspended leather saddles that are in reasonable shape, both found at the dump some time ago. Other than that, the bike will be built up as issued except for new paint and art. Brushed on paint job and art which I really can't afford but fun is fun and I do like street restoring old bikes.
