An odd battleship design: GB/BB/1910
I am not sure of the exact date when my friend Cliff had thought he would start production of the design, but I have dubbed it the GB/BB/1910. In the event, Cliff went with a different design than this, but the GB/BB/1910 was very compatible with what he had designed, previously. This ship has a very pre-Dreadnought look, with two turrets, only, one at each end. They just happen to be triple 12in/50 guns, though. The secondary armament is a very weak 8-6in QF guns in two-tiered casemates, in the forward and after superstructures. The boats would have been stored between the after funnel and the mainmast. This is the Springsharp report:
