Almost all USAF offices above the Squadron level had the IBM Executive typewritter as early as 1962. We had one in my boss' office in 1965, and at my previous base in 1963. It had a double function. It could type regular Courier font letters, but in the executive mode, it was most definitely a proportional font. I can guarantee this because in the mid 1980s I bought one at auction for $5.00.
It was used in the executive mode for OER [Officer Effictiveness Reports], AER [Airmen], and all letters to parallel or higher command offices. By 1970, I would suspect that any office that wanted one, had it. My TAS [Tactical Airlift Squadron] had one in 1968.
But, it did not have variable fonts and could not type super or sub script.
Second but. The IBM Selectric came out in that era, and it did have the capability of super and sub scripts. I never used one, so don't know for sure if it was capable of proportional balls, but suspect that it did.

None of my selectric balls carry the characters (digits) for printing super of sub scripts. Note reply #634

This one's even more suspicious. Although the Wild Bill guy is also suspicious - may have signed up just as 60 Minutes 2 did their thing, simply to monitor here for anything that might come up. The time frame would have been about right, IIRC. BTW - the Wild Bill guy only seems to come here when there is some sort of hot news involving a Dem created scandal attempt. Look at his / her posting history and you'll see what I mean. Of note, on a number of Sheehan threads ... FWIW ...

Of forensic note - this post was one of two this individual made, only on the Buckhead Rathergate thread - the longer thread.
