C5=9, b8=1 to solution.

This puzzle is on the second anniversary of the first isomorph of Champagne Dry (U240). Since that puzzle, the majority of the posted puzzles have also been isomorphs of CD. Admittedly, there have been others during these two years which were not isomorphs.

I would prefer a bit more variety in the puzzles posted. Does anyone else agree.

Best regards
