>Sounds like it became a Republic in 1963 to me.<
But the document in question was allegedly created on 17 feb 64. They would have used the current title correct?
So Republic of kenya would be right in this instance.
Sounds right to me. That's why I posted the World Book's information. It can't be changed on-line like wikipedia information can be.
Here's more from the Parliament of Kenya site.

“Uhuru Day:
The interim period of Internal Self-government, did not witness any major constitutional changes. The constitutional provisions finalized in February, 1963 remained virtually the same.At midnight on December 11, 1963 , Kenya regained Independence from the United Kingdom.”
