I purposely changed the bullets into "Z" myself in order to not screw up ascii formatting.

The original pdf file looks pretty crufty, which is why I assumed that it was typed on a manual typewriter (or perhaps an IBM golfball electric).

The document also may have been purposely put through N generations of xeroxing, to try to remove information about which printer it was printed on.

The added "cruft" is a crypto signature added to *every* NSC document in order to nail any unauthorized leaker.
