Here are some dupes and traders,I have seen NB chips as Norvill and Bailey for Club Harlem and not sure but Norvill and William Bailey I think were both owners one selling to the other?Looks exactly like the NB chips style of lettering and has the owners initials.The Frontier chip not listed and possibly one that has been made out of another chip and maybe a real chip just not listed? R N Roy Nelson chip from the Town House, Reno. Airport Club,Seal Beach,Ca is a beautiful chip and one of my favorites,the bomber chip they call it,very cool.Oceanic chip,is the S.S. Oceanic Club,Santa Monica,Ca. The Western Club May have possibly been used in Las Vegas and were used in Gardena Ca. another beautiful chip. Please leave a comment,question,suggestion,pic,poke etc. Torrey
