I haven't been able to find any further memorandum on this issue.
I'm not sure what dailies Justman was watching (I found the memo in a box and folder devoted to wardrobe items, not a particular episode).
The information I have indicates that "The Omega Glory" was filmed on December 18-26, 1967. I was under the impression that it took 24 hours to turn around dailies, but perhaps a date is slightly wrong somewhere, and that's the episode Justman was watching dailies from.
have been watching dailies from "The Doomsday Machine," though. That was filmed on June 20-26, and broadcast on October 20, 1967, months before Justman's insignia memo.
