dugrenier cigarette vending machine

Cigarette machine found in the Portifino Theater, in Scottsdale AZ, an adult art house that was part of the Art Theater Guild of America. Owned by Louis Sher, it was a nationwide chain with 40 theaters in 11 States.  The Portofino's history is interesting to say the least,  and the machine was rescued when the theater was torn down.  The only clue to it's age is the 40 cents it cost for a pack of smokes.   The only other information I have that might help is a set of numbers and letters stamped on the back, that I'm assuming isthe serial number   k 20 1046. 

Thank you in advance for your help!
