No, they did NOT have that key: A few had fractions (1/2, 1/3)...
BUT look at the "real" records from that timeframe from that squadron from that office on that airbase: ALL of the "real" records use "111th F.I.S." as a designation.
NONE use any superscripted fonts. NONE use proportional fonts.
It would be intersting to compare other memorandums to other people (from this office at that time,) with the Bush documents, which would tell us what sort of typewriter was used at that time. How could this be accomplished, military archives?
There was a way to manually roll up the paper half a line to fake a superscript back at that time, even when the font itself didn't have it.
But the letter spacing in the memos is too precise and too even to be an IBM Selectric or Executive in 1972. The memos don't have clerk's initials on the bottom, either (Lt. Colonel's in 1972 weren't known for typing up their own memos, either). The memos weren't on TANG letterhead. The terminology is wrong, too. The memos use the phrase "physical examination" instead of the correct term "Medical". The memos didn't have an acceptance box on them (mandatory for formal orders). The signatures differ on various memos, too. The memos are centered on the page. The memos have no CC note on them.
So there is *much* to question about their supposed "Authenticity." They strongly appear to be forgeries.

tttttttt
They appear damn similar to the ones in the memo. Notice that the superscript "t" is made automatically smaller than the usual "t". If any standard issue typewriter could do that in 1972, I would certainly like to know about it. Even the selectrics, which were state of the art then, did not have that capability as far as I know. Certainly you could go up 1/2 line to make a superscript, but it was the same size. You changed balls when you wanted special symbols, but I don't remember and haven't come across any that not only made superscripts but made them smaller, also. I vote for a forgery.
