Steve Sturtz included Classic production estimates in one of his books, but there were still many many many runs made after. Without any doubt there are more different JABO color combos of marbles out there in the world than any other maker by far. Vacor may produce more quantities of marbles overall than any other maker, but still limits themself to a limited number of color combos. That doesnt really answer your question, but the variety of JABOs out there in the world is mind boggling. If you add in Dave's other marbles at DAS, SMM, and Champion...his influence in the marble world will be felt forever.
