I stumbled upon an interesting Reno history web site, It listed several older gambling locations with a few photos. One shows a post card of the Skyroom at the Mapes Hotel. There appear to be at least four colors of roulettes on the table. It says the card is from the 1950's so I would think this is an actual color photo and and not a hand colored one. I was wondering if anyone knows what these roulettes chips looked like. the red chip up front looks like a plain mold with white inlay....C&S???? See link below
