Jay Myer Co. was part of Huxley. They owned the scroll mold.
Neither ever made a chip in their entire existence.
They stamped chips, yes, but the chips were made either at Burt or at Hispania.
For approx. 100 years every clay chip on the planet was made by either Burt, TR King, USPC, Paulson or Hispania.

Here is another fact you probably didn't know.
The Burt Co. made more Paulson chips than Paulson ever did (prior to their takeover by B&G)
