I agree with Jason, but just as he said it's more of an educated assumption than to be absolutely sure that it never happened. Seems preposterously unlikely. Back in the day, they weren't as wildly concerned about keeping track of records like that as some of us are now. The one thing I remember is that they always kept track of how many people had become five day undefeated champions. (A winner would be identified as the 63rd, or 76th, or 97th or whatever it was over the years.)
I don't have enough of a memory of what the winner received for their T of C shows, but my first instinct is that it was just whatever they earned in their game. Simply a second chance to play, if you will. I can find out for you, though.
