Don,
Below is Jim Perlowski's article on Cal's Gin Mill that he posted on the old Prodigy Board January 16th, 1997.

Lombarbi built Cal's Gin Mill in 1966. I realize Harvey Fuller's "Index of Nevada Gambling Establishments" lists a place called Cal's Food and Cocktails started in 1955. I do not believe this was Mr. Lombarbi's establishment. It wasn't. Cal had leased gaming space within the Rancho Inn from Wendell Tobler. A practice that was not uncommon in the 1950's. I believe this is why the first chips of Cal's were C&J's as well as the chips of the Rancho Inn also being C&J's. Cal's Gin Mill was built AFTER the Rancho Inn burnt down; (See article on Rancho Inn) this is why I believe Cal put a "new chip" with a different mold in play. Cal ran Cal's Gin Mill, which was a stone throw away from the Rancho Inn. The two establishments were both located near Las Vegas Blvd. North and Pecos in North Las Vegas. Cal's Gin Mill was larger than the Rancho Inn and had a full size antique crap table along with two or three Blackjack games. The usual number of slots and a special bar that had US Silver dollars inbedded in the top. Cal ran this place until 1980. He than leased it to a woman for a year who renamed it Cal's Jackpot. The table games were no longer active and ceased to exsist when this woman took over. In 1982, Cal took Cal's Jackpot back and ran it with an off and on Blackjack game and slots. The reason it was an off and on Blackjack game is because it was only opened when Cal himself was there to deal. This was usually on the weekends. The Cal's chip that was auctioned on November 22, 1996 was the last series of chips used in Cal's establishment. Cal's closed in August of 1996.
