To some degree, expecting consistency from Raleigh in the 1970's is doomed. There are many stories about Worksop just using whatever parts were available in the event that there was a shortage. How many models did the Nervex Pro lugs appear on over the years? The International was the one that they are commonly associated with. Bernie's Competition shows that they were used on Competitions too.... and how many paint schemes were used on the Competitions? There have been lilac versions in addition to Bernie's white with lagoon blue.

Were there Super Courses with Nervex Pro lugs? There's a BF thread on the subject, but no photos survive.

I suspect that this is one mystery that will remain unsolved.
