The mold can be called Langworthy, same as a HHR was a Langworthy mold. Langworthy never actually made chips. They were a distributer for Burt Co and Gamblers General Store. The chip pictured above was actually made by GGS, if it predates the selling of Langworthy. It could have even been sold by Wico but it was still made elsewhere.

I am not sure of the year Langhworthy was sold to Wico. ( maybe 1994)

Today the chip is produced by at least 3 companies, maybe more.
