Before publishing I found this while trying to see if there was a already a riddle like it out there (closest I could find was the 1000 barrels of wine riddle mentioned at the beginning): https://puzzles.nigelcoldwell.co.uk/ https://puzzles.nigelcoldwell.co.uk/ You can also think of this riddle as a very symmetric version of Wordle, where instead of trying to solve for a permutation of letters you're solving for a permutation of years.

Teh Guardian used to (?) publish puzzles by Chris Maslanka which were like this, and, as i recall, pretty good. There are a couple of books collecting them: https://www.worldofbooks.com/en-gb/products/the-pyrgic-puzzler-classic-conundrums-book-christopher-maslanka-9780434980758 https://www.worldofbooks.com/en-gb/products/the-pyrgic-puzzl... https://www.worldofbooks.com/en-gb/products/pyrgic-puzzles-book-christopher-maslanka-9780852650707 https://www.worldofbooks.com/en-gb/products/pyrgic-puzzles-b... This should be more of the same: https://uk.bookshop.org/p/books/university-of-the-mind-fiendishly-formidable-number-conundrums-christopher-maslanka/4449445 https://uk.bookshop.org/p/books/university-of-the-mind-fiend... The GCHQ Christmas Challenges might be worth a look too.
