I've had these two pool balls for at least 30 years, they are very old, the oldest anyone I have shown them to has ever seen, and I've shown them to some very wise experts. I have the 9 and the 12. If anyone can shed some info it would be very much appreciated. Iook them to Newell out in Clay Center Kansas, and he said he had never seen any this old, and that was at least 20 years ago. Thanks for your help!
