The Selectric wouldn't work but the Executive might have been used. However, it was just about impossible to center a name and address at the top of the page with the Executive. The technique you could use on Selectrics of hitting the backspace key for every two letters did not work.

What I find compelling evidence is the lack of erasures. It's almost impossible to type a full page - especially on a variable spaced typewriter - and not make an error. People forget, in the days before computers errors and their associated erasures were commonplace. The woman who invented White-out made millions. Why no errors in these memos? Because they weren't typed on a typewriter.

Your point about no errors in the documents is a great one.

I remember typing papers on typewriters when I was in high schools. It was torture to correct those errors, and they WERE inevitable.

The Executive had two (2) backspace keys, a 2-unit and a 3-unit. The characters varied in width from 2 to 5 units. So, as you can see, there was always a backspace combination possible for any letter.
