Tom,
I have chips with Red, Blue, and other color hot stamps. I will have to search files before I can find them. Can you scan your chip?

Is it injection mold or clay composition?
If it is injection mold, it could have been made by Langworthy, GGS bought Langhworthy. If it is clay composition, it was made at BURT. My guess is, it is injection and made at GGS.

In the early years after Bud Jones broke away from Christy Jones, he sold HHL, BTW he designed the HHL mold. The story of the BJ/CJ break up will be documented some day in the club magazine by HH. I just found a key piece of information for the story he is writing. BJ was actually screwed out of his half of CJ and Federal indictments over cheating devices were involved. It will be interseting reading.
