DavidHello, there is supposed to be a book on T206 cards coming out some day that may answer many of these questions. If you have specific questions, you can email me, and I'm sure Peter Calderon (email?) would be most helpful/knowedgeable. Alas, much information is lost in the sands of time, and we can't get closer to it than speculation.
Out of curiosity, what do you want the info for?
