Dr. Ang'awa if this is real is an interesting doctor to pick on as in 1962 by the above post office address of a document he submitted and if found in the Oxford Press, reveals his Post Office Box in Nairobi, Kenya and he is the big syringe handler in charge of the new program to wipe out tuberculosis in Africa with vaccinations.
What you found addresses the geography, though, so better.
Does Corsi do any research or does he rely on others and then does not check their work? Anybody know? Seems very sloppy.
There are copies in libraries but all are located quite a distance from me.
