So you are still trying to push that rope? I am afraid that you misremember what you saw on those IBM Selectrics. IBM Selectric proportional fonts looked nothing like
Courier. The point of these fonts was to approximate the look of typeset text in correspondence and other business documents. A
Courier-like proportional font would not have served the purpose. IBM offered two proportional fonts,
Boldface and
Title.
The font most similar to
Boldface today is probably
New York.
Title was a bolder font that looks kinda like
Optima. As I told you in my previous post,
American Typewriter is a proportional font that is designed to be reminiscent of
Courier. However, IBM offered nothing like
American Typewriter.
If you need reminding of the fonts available on IBM typing elements, then you may find them
here. Scroll down to the scan of Page 12 to see the Proportional Space Correspondence Typestyles.
