The point you are making may well be as true as summer rain, but may be equally irrelevant. I believe it is very possible that despite the lack of the word “Republic” in the 1963 constitution, more than likely a British concoction, the intent of newly independent Kenya was to establish a Republic from day one, and this intention may well have been manifested in the terminology they used to describe themselves as they went forward.
The use of the term Republic of Kenya on this form may be meaningful or it may not be. In order to know, someone who KNOWS what similar documents issued in Kenya in 1964 actually looked like needs to make such a detemination.
And that’s not you or me.
If anyone has a similar document, issued in Kenya in the time period in question, and which provenance is known, were to post it, this issue might be settled.
A forger would get a copy of a Kenyan COLB for a birth in the same time frame and then copy/modify it.
I’d much rather see the original bound volume of the birth certs!
You can bet it will be a frigid day in Hades before that one sees the light of day.
Tell ya what, if my name was E. F. Lavender, M. H. Miller, or Joshua Simon Oduya, I’d be sweatin some serious freakin bullets right now!!!
