John D.F. Black who was the original Star Trek story editor for the first part of the first season (also wrote "The Naked Time") wrote an envelope script for "The Cage" which was the precursor to "The Menagerie." It was never used but is a part of Trek history. I have part 2 which is really interesting but I do not have part 1 and was wondering if anyone has a copy of part 1 of the script they could share. Any help would be greatly appreciated.
