Don't forget the wordwrap smoking gun:
...others have noted that the wordwrap of a manual typewriter is different than a word processor.
But to analyze this facet more specifically, MSWORD wraps the current word when the end of a word passes the right margin, whereas a person typing manually finishes the word he is typing when the right-margin bell rings, and then does a carriage return. The net effect of the manual typewritten style is that, if one draws a vertical line at the bell-margin, that line should go through (intersect) the last word of every line of text.
Clearly, from the 1 AUG 1972 memo, NO SUCH VERTICAL LINE CAN BE CONSTRUCTED THAT INTERSECTS THE LAST WORD OF EVERY WRAPPED LINE OF TEXT!
For example, in paragraph 3, on a typewriter, we have to assume the right-margin bell rang while typing the word "and" on the 1st line. Yet, if that was the case, then on paragraph 2, the margin bell would have rang while typing the word "orders", and the subsequent word "for" should have appeared on the next, not the same, line.
Oh, yeah, "margin bells" ... forgot about that!
Ask not for whom the right-margin bell tolls --- it tolls fo John and Terroreeza !!!
This election is beginning to be fun.
