There has been so much misinformation here about the technology of 1972, written mostly by people who weren't even alive then, or by people who never used the modern office equipment of the day.

Even the most experienced typist, with the most expensive proportional typewriter, and all of the wiz-bang replacement keys could not duplicate the kerning used in modern word processing software and laser printers. These documents clearly display this kerning.

Therefore, there is no way these documents could have been typed on the dates identified in the documents.

Exactly. Which is why wasting time on things that can be disproven is just that...a waste of time. All you need is the overlay of the Word document and the memo. While individual aspects could be reproduced, the documents would still be different. Heck, two docs from to different typewriters wouldn't overlay.

The overlay is all that's needed. The rest is arguable. That's not.

To let the rest of us know what kerning is see this Adobe kerning explanation

If I may be so bold as to summarize. Kerning is varying the spacing between letters based on what the two lettters actually are, rahter than just how wide they might be. Thus a "T" and an "A" would be closer together than two "A"s or two "T"s, because the "A" has overhead room to accomodate the top of the "T".

From the adobe site:

Kerning

Kerning refers to data included in a font that specifies how to adjust the spacing of a specific pair of characters in a font. The following example illustrates a word that uses kerning, and one with no kerning, using the default spacing in the font.
