Note how all these ‘strings’ appear to be of consistent length when compared the text of box 6c which reads:
Name of Hospital or Institution (If not in hospital or Institution, give street address)
Unless Hermitian wants to argue that all these documents have been forged, the conclusion is logical and inescapable.
Estimating original font size from documents can be quite complex as you need to understand what scaling steps may have been applied. The best way to compare is to compare with text that is consistent, such as the header in the boxes of the long form birth certificate. You can now do a relative comparison. I believe that my findings are strengthened by the pictures below
Looking forward to Hermitian’s response.
