There is a real world and in that real world these docs are either legit or they are not. Nobody's motives matter here. There have been 100 really dumb right wing "proofs" of forgery, like the proportional type thing.
Don't worry about anything having to do with formatting -- proportional spacing, alignments, centering, etc.. 1970s business machines could do all that stuff.
Try to find this type face in an actual TYPED sample. We know this face exists on computers and in fonts on the internet... the question is whether this face appears in a TYPED document from the 1960s-1972.
All that matters is basic letter shapes. Proportion and weight and shapes of strokes cannot be determined from degraded xeroxes. And alignment of letters, baseline variance, etc. cannot be discussed from degraded xeroxes. All exercises involving blowing up type, etc. are useless because these are degraded xeroxes.
We need an IBM type ball face that looks like this:
