I'm trying to determine if these front strike matches from Charleston Park Restaurant should be on the Chipguide ??

The Mt. Charleston Lodge burned, the first time, in 1961. See this article:

Are these matches from the restaurant and lounge that were added in the late 1960's ?? In 1968, Two separate articles in the Las Vegas Sun referenced Frank Sennes Charleston Park Restaurant. Surely one of our members (Phil) may have stopped in for a beer and can verify if they indeed had slot machines ??
Thanks so much for any help in figuring this out.
