It'd be nice if people read the thread sometime but maybe that's a lot to ask. I took half an hour of my day to research this rather than speculate and provided multiple examples I found online of the matching 1977 Raleigh Rapide (UK/Euro spec) and others have acknowledged that the "mystery" is solved.

And yes, there were plenty of Super Courses with Nervex Professional lugs built around 1971-72. I saw a nice coffee brown one in person the other day and there are currently three or four of them for sale on eBay and locally here on Craigslist/Facebook. Nothing uncommon about them at all and there are lots of them posted in the "Show your Super Course" thread here in the C&V forum. You can also type in "Raleigh Super Course Nervex" on Google Images and immediately see several fine examples without so much as scrolling.
