I've gone through all of them and have not found one that matches the same type used in the CBS memos.
Aside from the typeface discrepancy, Killian signs his name Lt Col (Not "Lt. Colonel") and the dates appear with a 3-letter abbreviation, as in 6 Sep 73 (rather than "18 August 73). Way too many discrepancies for someone who probably wrote reports and memos every single day as part of his commander duties.
