The cue he used was his own original Meucci Ivory Crown Jewel made by Bob himself. Here is a pic of my own 70s Ivory Crown Jewel and the two shafts at the bottom with the black ferrules are the actual shafts Jim Rempe used in that tournament. They are very skinny and ideal for English 8 Ball.
Wish I knew where Jim's actual Ivory Crown Jewel was!
Damnit Si... if I'd known you that cue stick years ago, I'd have been loking to buy that beauty from you instead of the Carolina Custom, Kenny Murrell or some of the other cues I've bought from you over the years
