Paul Indy, the owner of Paul-Son tells me the Diamond Mold is a Paul-Son Mold. He calls it the Todd mold. This is the mold we accredit to the Jack Todd Co. Jack Todd is or was the distributer for the mold. Paulson went into business in 1963. I came home and checked my chips and I have diamond mold chips issued way before 1963. My guess is Jack Todd transfered the diamond mold from the Burt Co in 1963. Will post results of this hunt as soon as I get them. Gee, I love the history of chips.
