I really like these chips and been told the SKY--- was a Colbrandt's chip and have seen flips marked with that name too. I have also seen someone that had a SKY--- on one side and a Flamingo on the other giving it the impression maybe it was Colbrandt's Flamingo, Reno like the one on pg 211 in James Campiglia's book. Another similar chip someone else showed me said Pioneer Club with the wagon and a Flamingo on the other side, the exact 2 pictures on pg 211 and 130 on one chip. Both chip were in this small circle mold,which I like a lot,so cool. Now the BYD I would have to guess, like maybe Wyoming or Idaho? I could be way off,but would really like to know,these are really cool chips too and have, I think 1 or 2 other colors from here,thanks and if you know leave a post,Torrey
