That's a nice bike, I'd be interested in seeing how the geometry compares between the Raleigh Pro and that. The Carlton has braze-ons on the top tube though, where the Raleigh Pros from the early 70's (as far as I know) never did.

That's a stunning Carlton. Being a Derbyshire lad I do have a soft spot for 'em. Those lugs were available on some of the Raleigh Professionals as well, I think *some* of the late sixties/very early seventies models had these lugs. Here's one:

Most of the Raleigh Pros had the Italian-style pointed lugs, rather than the British fancy lugs.
This Raleigh Professional is definitely the correct colour though - I've bought it off the original owner, and it's never been altered. In 73/74 they tended to come in either Blue/Silver, or Black/Champagne-Mink. The blue ones are more common, as I think they're more aesthetic. This catalogue page shows the '76 model in the blue.

TI Raleigh didn't start until 1974; the Raleigh Pro didn't carry the TI stickering until much later, I think - the Raleigh catalogue linked early shows the '76 Pro without TI decals.
Another point of note: I've been messaged by Gary on here, that sizing is something to be mindful of on these, as it has a higher BB due to criterium races and the fear of pedal strike.
