Hi Jarl,
Thanks man, thats handy - I spoke to an Mil expert in African watches - seems it is most likely Kenyan AF.. so post further down with my findings. I even had someone else contact me with the same markings but a different number.. see posts further down below.
It could be South African Airforce, but all the info is pointing to the Kenyan AF (82 AF), named after the mil-coup attempt in 1982.
