This font was used very frequently on Square Square Diamond (SqSqDi, top row examples) and on the Square Square Rectangle (SqSqRt, bottom row examples). There are a couple of exceptions (e.g. two hub mold chips) but it is almost never found on any other chip mold as far as I can tell. The vast majority of the chips with this font are associated with California establishments, mainly from the 1950s to the 1970s.

As far as I can tell, it is not one of the 25 or so fonts identified in the front pages of the 2017 5th Ed. of The Gaming Table.

What is the font called and who used that font? I am hoping that if we can identify who used that font, we might be able to identify who owned or at least primarily used the SqSqRt mold (the lower one above).

According to Eisenstadt, the SqSqDi or DiSqSq mold was always an open mold, open to all distributors of Burt chips, and many of them used it.

The SqSqRt chips have a stranger pedigree. According to Borland (1988) and Herz (1995) T. R. King was the first owner of the SqSqRt mold. This is odd because none of the T. R. King order cards make reference to the mold. The chips seems to be of USPC/Burt Manufacture. (T. R. King did make some ZigZag chips in the 1990s, but they are different in composition from the Burt ZigZag chips. They are called "Wreath" mold in the T.R. King order cards. )

There is a single uploaded Burt order card for SqSqRt. It is a 1962 order card from "California Game Supply Co." located in Pasadena for Nevada Club (LV, NV) inlaid chips.

Do you think this font was owned or at least mainly used by California Game Supply? Do you think that other distributors used the font?

Any thoughts or hypotheses are welcome.
