Larry,
Since you are from Indiana this information may help you, I’m sure that the Illegal collectors will respond with specific names and addresses. Keep in mind that in the 1930s and 40s these operations were truly illegal so the operators frequently used distributors that were within driving distance of their base of operation. For example, William McBride sent his son to Chicago to pick up the red, black, yellow and gray T mold Indiana Club chips. His son, who was fresh home from the service, jumped at the chance to go to the windy city. He has been a great source of information about “The Joints Of Jeffersonville"
The following are examples of the mold designs that were most common in the Jeffersonville area during the 1930’s and 1940’s.
