I'm curious where you based that drawing upon, if I may?
Everything I've ever read about the Lion's Mark II L/45 (in Mark II turret) has indicated that their turrets would be based on that of the KGV class, with the slab-like zero degree inclination and the apparent 'offset' fron the front of the barbette, and also without visible blast bags.
I took made these based upon the reference i had for lion class.
They probaly dont have blast bags, but they are surely as big as that.
And the turrets you see in the first picture are kinda small...
Since everything here is based upon one scale.
The 16 in mk I is 18.86 meters long. Plus the barrel from 18.38 meters long.
In the drawing from hood it is 20.5 meter long turret+barrel.
16.74 meter is missing here...?
