    Many thanks Peter.

    Is this square opening in the interior wall of this type 28a also for ventilation, or simply for communication between the two chambers? It's somewhat lower down than the vent discussed above. This pillbox is also on the GHQ line near Hartford End in Essex.

    EDIT: I think I have just found the answer on the Pillbox Study Group website where it suggests such an aperture is for "observation, close protection and possible venting"

    Yes, the primary purpose was to be able to shout to the occupants in the adjacent room and sneak a look if there was suspicion that the enemy had got in, and use it as a pistol port. Being an 'ole in the wall' it would give some cross ventilation. Not protected against grenades......
