Langworthy was the 1st company to produce it. Langworthy does no longer exist. It was sold to Wico, and returned to Gamblers General Store(the original owner) in the Wico bankrupsy. You can find the chip in GGS catalogue and at Atlantic Standard's web sight pokerchips.com. The only way to tell who made the chip is to ask the casino using them, where they bought it. If it was made in Asia, the casino bought it from a distributer and would have no idea, who made it.
