The story of these gun mounts is (in the real life) that the british have choosen an american twin mount (MK33 ?) but with a home (!) made protection.
this consist in a "half" turret with a metalic part and "canvas" top and side, this turret is unique and only used on the Victorious:
see the turret without the upper canvas and the lateral "curtain" opened (barely visible) here:
And the turret enclosed:
the metallic part
At the beginning, when I drew the VIC i only have a front view of the turret, so i drew it viewed from the front , as found in the original drawing:

When bombhead made the renewing of the drawing, he made a profil view (and a top one), see here

and with more photographic and drawings reference, i try to drawn it - it is like it is now...
this turret is very curious in shape and it is difficult to reproduce it correctly.
PS: i will change the 3 pixels barrel ASAP ( i was a litlle too enthusiastic
)
