JSB,
If you are responding to my post, I was not suggesting anything. I was merely pointing out the correct dates that the armour belts were altered in Repulse and Renown.
However, for what it's worth, I do not think either ship could have been fitted triple 14" turrets aft unless modifications were made to the rather fine after-run during construction. I would agree though, that a significant reduction in either speed or in the scale of protection would have to be made in order to incorporate triple 14" turrets into the design. I'd suggest that the ships' beam would have to be around 100 ft, not including the bulges.
Meanwhile, I forgive you.
