HC#3 is an old Harolds Club, Reno roulette from Table 3. Although not valuable, it's a real challenge to get all these 1950's H-mold roulettes. I know of tables 1,2,3,4,5,6,10,11,12,13,14,15, and 71. Generally there are six colors per table, although there are some variations, maybe due to fading or reorders. Table 13 is extremely tough; I only have an unused white chip, so maybe #13 was never opened.

There was a thread on the bb a few days ago about these chips with rubber-stamped numbers on the, apparently done for a home game. I've seen the numbers 5 and 25.
