I don’t think it’s a problem.
The comment on that site about the Republic of Kenya not being in fact until 1964 is TECHNICALLY correct, however they issued a constitution in 1963.

THE CONSTITUTION OF THE REPUBLIC OF KENYA, 1963
Now it was officially recognized by the government of Britain the world in 1964, but in 1963, when they declared their independence , they considered themselves The Republic of Kenya.
If Im not mistaken, The United States of America wasnt recognized by Britain as soon as we declared it. Only after being defeated in the war did they accept it. But we WERE the United States of America from the date of declaration.
That’s the amended constitution. The original 1963 constitution made no mention of “republic” at all. I examined it here: http://www.constitutionnet.org/files/KEL63-002.pdf
If — that’s IF — that doc is the entire original, you can search high and low and not find the word “republic” in it. I also looked, all day, at various places, at ebay and other merchant sites for Kenyan stamps and currency, at newspaperarchive.org for contemporary references, at Google images, you name it I was in it, and I couldn’t find anything.*
That’s not to say the words “Republic of Kenya” could not have been on official paperwork in Feb ‘64. Stranger things have I seen. But we need to round up some 45-year-old Kenyans to confirm it because there’s nothing on the internet.
*Ok, one place I didn’t go...genealogy sites. I’ve taken the pledge, no genealogical research. :)
