First, thanks to everyone for some great sites for interesting props.
Second, since you've brought up the different dice shapes, I checked my box game covers of the Trebeck and Martindale versions, and you are correct - they aren't the same - so why did I get the answer I got to my question? Probably because I remember that when I asked the question, I worded it "Where did Merrill Heatter get the dice he used on High Rollers?" By not indicating which version, it could well have been answered in reference to the NBC run. I probably shouldn't make guesses that make me seem like a doofus. Anyway, I appreciate y'all. G'night -
