Upper Deck & Shield Deck|
We are now in the Shield Deck, outside the Forward Gun Turret. On reaching this level the shell is tipped over and placed on a sling and transported via the "Transporting Rail" around to the left or right side entry port in the side of the turret. It is then passed through one of two entry ports into the Turret after having been suspended from another hook. Note the "Turret Pointer" in the top left corner.
