Incorrect.

Also incorrect. (That is, if you're specific to the Super Course. This statement is too vauge to be considered factual though).
The early '70s Super Courses were odd beasts when it came down to bottom brackets - I've seen some running 26tpi threads, and some 24tpi, and both were equipped with a cottered, steel Stronglight crankset.
As for the mid '70s Super Course MkIIs, I have no idea as to what type of threading they used (or if they used both, as with the earlier models).
The later 1977 (the un-official MkIII) Super Courses (the ones running cheap SR cotterless cranks), were equipped with 24tpi BBs, and are probably the only Nottingham SC variant you can rely on for BB uniformity.
The Panasonic-made ('83-'86) Raleigh USA Supercourse BBs were always threaded 24tpi.
Take care,
