For about 10+ years the only Monte Carlo I knew of was the gray Monte Carlo roulette. I wondered if it was even a roulette. Then, out of the blue, the other 6 colors showed up. I believe three sets of chips were sitting with a distributor that sold its inventory. I think Bud bought the distributor out.

I think (I could be wrong), that the three sets of Monte Carlo roulettes are the only ones ever to be found

So, maybe more DI colors are out there.
