Nope. The overall spacing will remain but on a per-character basis you can't tell anything. The "fr" ABC spacing is a perfect example. I can't tell if the "r" is underneath the "f" or not because the resolution of the fax is too low. The resolution of the fax is probably 1/3 that of a printer which means the C spacing on the "f" is not discernable.
I think these docs are fakes but these available faxes make it difficult to be definitive.
I don't mean to be rude, but in a document of any length, the letter spacing adds up, and the blurring of individual letter pairs is of no consequence. This is demonstrated by the failure of even low-res scans of alternative documents to match at at the word and line level.
