7) To effect this the floor of the loading gallery was lowered 3 feet.
Upon the second occasion one of the guns had been mounted in the open at the factory behind a dummy parapet and loading gallery.

This was because both guns pointed into a central loading gallery located between them, which for the greater protection of the two detachments had the elevating and compressor gear mounted on the rear side of the mountings when they were in their loading positions.
Each gun detachment consisted of 14 gunners (26 when both guns were operated together), 5 of whom were underground in the shell and cartridge stores and two more constantly in the loading gallery.
This took several months and many site visits to check and double check the geometry of the emplacement and loading gallery.
