I have recently obtained copies of many of the LGSQUR mold files. This is the mold with alternating horizontal & vertical rectangles. I will be happy to try to ID as many UFC's as I can.

The most startling discovery I have found so far is that the Newport Club chip that everyone assumed was from Newport Beach, Ca, was used in Morgan City, La.
It must have been a large club as there were 9 different chip orders between Sept. '59 & Feb. '65.

Most of the card files are from LA or MS. The only NV chip order was for Railroad Pass Casino, Henderson, the Gray no value chip, N2035, made in 1957.
