Search for The Magical Typewriter
So now Rather needs to produce a 1972 typewriter capabale of all of the following:
Proportional TNR font
13-point vertical spacing
Perfect centering of proportional fonts
and it must be commonly available enough to have been on a Colonel's desk and all features described above convenient enough to use that a CYA memo would be typed using them.
Feel free to correct me if I missed anything or made any mistakes.
BTW, the last three appear to be impossible for a 1970s typewriter to have managed.
