Nope. Not on a proportionally spaced typewriter (had to type in each line twice with no errors) from back then. That was the realm of clerks and specialists and typesetters, not doctors or officers, and certainly not for a memo.

That makes sense. So, memo to what file, typed by what clerk? Where are the initials of the typist? Why does the memo show up in the man's papers, if they are part of an official file? If the non letterhead memos are CYA documents for his personal use to take home, why have them typed in such a manner, and expose these "office politics" and CYA antics to a clerk, when a written note would do?
