I worked in what was then Eastern Region from November 1962 to March 1964. A large part of my work was fixing trig points for a town map of Port Harcourt. It was quite a tough tour and I had Malaria quite badly but I really enjoyed my time in the country. I have far more pictures than the two posted here.
