Interesting additional facts there.

Some connection with Langworthy and their HHR mold would make sense.

Sheer speculation here --- You know how C.J. Sisk Company was the California name that Paul-son used when selling to the California market? I wonder if Langworthy operated in the Nevada market and used Golden State Club Supply (separate company, but some affiliation?) to sell to the California market?

Anyway, I find the origins of chip molds interesting, but puzzling too! Manufacturers, Distributors, Mold Owners, Open vs. Private Molds, Territorial differences in USA and abroad, etc. etc.
