Do you think this chip might be related to the Flamingo/Pioneer chip? I have it as being from Colbrandt's Flamingo Club in Reno. I also have this singleton die with the same "SKY ---" logo. I did find the die in the Reno area - I know that doesn't mean its from Reno after all I found a set of Vapors (Littlerock) dice in Redding, CA.
