In my search for the origins of old molds there is one other item chippers should know. The Burt Company did not hot Stamp chips. They felt hot stamps were easy to change and therefore easy to counterfit. Thus if a distributer ordered 10,000 HHR chips without an Inlay, the distributer put the hot stamp on. Burt had no records of where they were used, only the distributer that placed the order. The records are not computerized and they are way too busy to do searches. I am told TR King will do searches for a small fee. I have not got around to TR King yet. Atlantic standard is still making many of the chips used today.
