I got mine from Sue Wells. She is/was a Club member. She lives in Biloxi, MS.
John Romeo was a big illegal operator in Biloxi. I met him at the Biloxi chip shows put on by Bob Gable. Got quite a few of his chips from him.

Sue sent me some more chips from John in 2007 including the B chain chip.

John said he used the B chains at the Broad Water Club in Biloxi in 1940's-50's.
