The document is a 1964 certified copy of the an original 1961 birth certificate. The Deputy Registrar is certifying that the information contained in the copy is same as original, and, I would presume, that required signatures were present in original.
If the latter, it is probably fake, as the IBM Selectric wasn't introduced until 1961, and it is difficult to envision it importation to this hospital in Kenya by 1964. Eventually, it achieved 75% of the US market, and so a forger would probably find a Selectric to use for the fake.
To me, the typed sections appear uniform, and thus likely produced by an electric golf ball typewriter, rather than the uneven result from a manual basket typewriter likely in use in Kenya in February 1964.
