He went to KC and did extensive research on JT Co. He wrote several articles on them. Some were published in Gaming Times, Bill Akemans magazine.
JT made many illegal club chips for the illegal joints in the Troost St area of KC.

Paul-Son bought the diamond mold, I would assume from the Todd family. Jim Blanchard could share some light on the purchase, maybe. I sent him this link.
If PS bought the mold from the Todd family, there is every chance the records came with it. I have repeatly asked PS to search their warehouse. No luck to date. If PS bought the mold from Burt, I agree the records probably don't exist.

Club member Chuck Smith has found several chip ID's for me from the Troost St clubs, searching the library in KC.
