The
Carlton is, indeed, a pretty nice bicycle. Now, before jumping into money spending, you need to know if the
bike will fit you, once built...
It would also be a good idea to ensure that the
frame and fork sets are straight and not in serious need of repair. Remember, vintage light weight bicycles were/are fragile and often times pass through time experiencing some misalignment.
So, were I you, I would let us see some good clear pictures of the frame and include measurements. Let us know how long the seat tube is, measured from the center of the crank to the center of the intersection between the top tube and the seat tube. Report, also, your inseam measurement (floor and snug to your crotch). That should help determine if the bike will be an acceptable fit, or not.
Good luck with the bicycle. It is a worthy project, to be sure.
