Good luck on your search. I hope you find the ones you need.
I've been working on this set of roulettes for a while, too.
I still need 13 of them to complete my set.

See my picture, attached, for the ones I need. This is a photoshopped picture. I don't know if these are actually available in the colors / graphics shown.

FYI, at one time Doug Smith was looking for the green "roulette wheel" chip that you show. I don't know if he still needs it or not.

If you do come across any of the 13 that I'm looking for, please let me know. Thanks!
