If you wonder how do you get things up and down the access shaft, well here is the answer. This is a first issue (1968) Cargo Net. Place items within the net, attached the hook through all 4 metal hoops and pull the rope up the access shaft. The rope was fitted to the top of the ladder and lowered down by a crew member above. Heavier items may require 2 above ground to raise or lower. Caution had to be taken as the items would quite happily swing and twirl about as they were raised or lowered. The joys.
