I know it was used in books, presumably properly licensed. Since typewriters (even the Composer) couldn't handle it technically, I doubt the question of licensing it to typewriter manufacturers ever arose.
Yes. And so the "expert" comes on the television today and "testifies" that this is consistent with technology that was available at that time--and those people who say otherwise are lying. This is how the Left operates. They omit the word "readily" (as in "readily available). They can then disparage the argument questioning the validity of these documents.
