The putative draft was in LHO's alleged handwriting and, interestingly, had different spelling errors than the typed-up letter.
Ruthie originally said she read the whole draft (and decided to copy it) when she found it folded up and lying on her desk secretary in the living room on Sunday morning and happened to notice that the very first sentence was a "falsehood" about the FBI's allegedly no longer being interested in him, so she felt compelled to read the rest of it just to see what other falsehoods might be in it.
And boy-oh-boy did she find a bunch of them, so she decided to make a copy of it.
That sentence is in the middle of the draft (and typed-up letter), however.
After the draft had lain there on her desk secretary for "two whole days," she hid it from LHO and Michael Paine while they were moving the living room furniture around for her, and then she stole it . . . and implausibly waited until 11/23/63 to give it to FBI Special Agent James Hosty.
Who knows about Ruth Paine, although she may have been a type now nearly vanished from the American scene: The New England nosy, busybody do-gooder, politically active community spirited, a touch of Puritan.
I last lived a year near Boston in 1962, and among the older ladies there---the League of Women Voters types---you might see a version of Paine.
As for LHO, though people say he had dyslexia, evidently he actually may have had something called dysgraphia.
So LHO would misspell words at random, sometimes differently in the same letter.
LHO's spelling has the unfortunate side-effect of making him seem unlearned. I wonder what the image of LHO would be if he had grown up in the era of spellcheck
