It clearly shows a reference to "The Republic of Kenya" at least 3 months before the date on the Kenyan BC. Several people here have declared this document a forgery because they claim there was no such place as The Republic of Kenya until December 1964.
Well, obviously there was.
Nice Find!

Post-colonial history
The first direct elections for Africans to the Legislative Council took place in 1957. Despite British hopes of handing power to "moderate" African rivals, it was the Kenya African National Union (KANU) of Jomo Kenyatta that formed a government shortly before Kenya became independent on 12 December 1963. During the same year, the Kenyan army fought the Shifta War against ethnic Somalis determined to see the NFD join with the Republic of Somalia. The Shiftas inflicted heavy casualties on the Kenyan armed forces but were defeated in 1967.
