I can't speak to the authenticity, but it was a pretty crappy typewriter. The shift misaligned the capital letters seeimingly at random. (K,E,A,O).
Anyway, Q only lightly touches on the birth certificate (1429) so this is probably a slide.
BTW, another Q post number that ties in to legislation with the same number and topic.
8 USC 1429 is "Prerequisite to naturalization; burden of proof"
