Per Kling's book the Murray's Club was licensed for three table games and sixty slots. Harrah only leased the eastern half of the building for his Black Out bar for one year. I would have to assume there were some chips used at Murray's Club, owned by Murray Jacobs, but where they these MJC chips - don't think we can know for certain since no manufacture's records exist for the AroDie chips. This guy might have been as close as we can get to someone who knows since the club only existed from 1942/3 to 1952.
