Did a typewriter in 1972 have built-in automatic kerning? Let's not get bloody ridiculous. Even if you could dig up some advanced, expensive equipment back then that could with a lot of tweaking recreate these documents, what would be the chance of a simple military memo from a small office being written on it? And match perfectly a document written in Word today? Zilch.The chances are about equivalent to smashing your Timex watch, and having said parts spontaneously re-assemble themselves into a Rolex.
