Kurt, according to the catalogs online at Retro Raleighs and Mark Bulgier's site, the Super Course does not appear in the 1967 catalog (though there's a Raleigh Carlton that's pretty much the same thing) and first appears in the 1968 catalog as model DL 100. Pic below. Of course, the 1963-66 catalogs aren't there, so I don't know if it's a model that appeared earlier and then went away for a few years.

I'll add in the other catalog pages from what's online or what I have in a bit.
