The video frames Orion and King George V as the first British super-dreadnoughts rather than jumping straight to Queen Elizabeth. Their 13.5-inch guns and ten-gun broadsides made a sharp break from earlier 12-inch Dreadnought batteries. A triple-turret experiment dated to 1909 would therefore sit beside an active change in both calibre and broadside weight. That timing makes the photograph historically consequential even before its identity is proven, because it points toward an alternative branch at the start of Britain's super-dreadnought program.

Where a triple turret might fit in super-dreadnought design
The proposed timing places triple turrets alongside the Orion and King George V classes, when 13.5-inch guns and ten-gun broadsides redefined British battleships.
