Travis,
I agree, that is one of my favorite chips and one you seldom see. For a long time the only place i saw one was in Robert Eisenstadt's header for his coded antique chip sales. He had a red one but, it was a little rough around the edges. I contacted him when I first saw it. He had no dupes to sell. Then just a few years ago a fellow collector mentioned he had several colors of that chip. They were in SWEET condition. So I was able to buy/trade for a blue one. That chip was not even in Dale's book.
