Not to my knowledge, more an ok to copy/display a page for fan discussion/modified rules.
No idea what the rules are now if Marc doesn’t own it anymore.
Side note, I am rather a fan of these books, one of which was a redo of the careers, Book 9, Traveller plus. Book 10 is combat update with custom gun build and armor rules. Might be worth a look for you CT Redux folks.
