Syke, thanks for that info; unfortunately, my lousy photographic skills don't show the decals well, but the "Raleigh" transfer on the downtube is cursive rather than the block print of the post '73 Super Courses. I actually also have a '73 with the block style and a '77 with the same (yes, I seem to be collecting Super Courses). Really, everything on the bike looks the same as the Super Course featured in the 1970 catalog except for the headbadge: http://www.jaysmarine.com/TH_Raleigh_Cat_70_6.html. And the 1970 catalog describes the derailler system as Huret Luxe, which is what's on the one I'm showing in the pic. Perhaps there was regional variation, just as you say.
