Thanks for this image. It explains a little better. I was going through older posts and was looking at one of yours. I was still a little perplexed.
For myself and others, Is the crux of this matter the fact that those 2 entries were supposed to be blank?
Yes, the 9s in those two boxes would make sense to explain blanks as in "not stated." Something is amiss to these pencil mark codes, but since it's a forgery, the pencil codes marks belong to someone else's birth certificate.
