Don,
These Pimadonna roulettes are definitely from Jean(then) now Primm, Nevada. I harvested some #2 gray roulettes in the exact same style from there on April 25, 1994. The #2 gray is the only one from this series that I have in my collection. A year later on April 23, 1995 when I stopped by again they had changed to H&C hotstamped roulettes and I harvested some #1 blues and #2 yellows.
Till later,
Mr. Roulette
