This capability simply did not exist in 1972 on any typewriter.
Did not exist.
It's different than "proportional spacing".
It's actually even worse and even more unlikely than you have shown, for even if Killian had been able to do all these things mentioned, there is still a ZERO chance that Killian or ANYONE, back in 1972, typing on a then existing machine, even with great effort and precision could precisely match a document format not to be in existence for another fifteen years - through sheer coincidence and dumb luck.
The chance of that happening is indistinguishable from the chance that a chimpanzee could sit down in front of a typewriter and compose a limerick - and not just any limerick - this PRECISE limerick:
CBS replaced Cronkite with Rather

His indiscretions grew bolder
And his words became nothing but blather
i.e. vanishingly small. ZERO. Ergo, the documents are recent computer generated fabrications.
Case closed hard.
