I don't have a good copy of all the available IBM fonts so am reluctant to opine on this.
One of the web experts said that the 4 with a closed top and no foot was used ONLY in Times New Roman and that Times New Roman was ONLY on computers.
Well, I went to the Linotype website and they used Times New Roman, with a four with a closed top and no foot, on Linotypes. Created 1932.

Admittedly Killian probably did not use a Linotype machine for his memos. Still, we want to kill this story, best to be cautious.
I posted this on another thread.

This version of TNR did not exist in 1972. It's usually a default font in MSWord.
I've speced type for 20 years, and nothing annoyed me more than documents processed in TrueType TNR when they were supposed to be in Times.
So, last night I glanced at the first document. Saw the kerning, the font and the letter spacing and laughed out loud.

As I understand it, Times New Roman is indeed an older font but it was used only in typesetting for newspapers, books and other material printed in printing presses. Linotypes are typesetting macines.
However, until the advent of word processing computers, Times New Roman was never available as a typing font.
For example, the "Old English Text MT" font that is now available on Microsoft Word may have been an older font used in books from, say, one hundred years ago but that particular font may never have been offered to the typist at home or at the office prior to the advent of computer word processors.
As I understand it, Times New Roman was first available as a typing font for home and business use when it was included as a MacIntosh font in 1980.
