Since it's been repainted and has some rust, I'd have it media blasted and then brush-paint it myself (when weather permits).
- Maybe a very proper Navy, with a cream colored head tube and seat tube panels, that would show off the aftermarket decal kit, with the black Carlton ST decal and the gold DT "Raleigh" in script.
Then I'd get a brown Brooks B17 and matching cloth tape.
I'd rebuild the wheels with new ss spokes, and do all the bearings hoods tires & etc, and install slick cables with new lined housing, lose the dork disk, and and a new HG 5-speed FW and chain.
I'd keep the other components as they are, though if it was to be my main ride, I'd store that Jubilee and install a Huret Challenger instead. (I ride both but much prefer the shift quality of a Challenger).

Then I'd polish it all to the nines, and install a brass Crane bell on it.
- And unlike many of my C&V compatriots, I would do all this even before I rode the first mile on it.
It would be a super fun project and there is no question you will love the bike.

After all, it's a Super Course, and in my very HUMBLE opinion about Super Courses, you would have to be a MONSTER not to love a Super Course!
