Agincourt as a fast 18-inch-gun possibility

Has there been time to research the Agincourt question yet?

The ship sits between competing interpretations, but a 28-knot design would require small-tube boilers and likely points toward triple 15-inch guns or six 18-inch guns.

Agincourt remains an unresolved design puzzle. The claimed 28-knot speed points toward small-tube boilers, but both those boilers and heavy guns were long-lead items. Speed, machinery, and armament evidence can therefore support different reconstructions of the proposed Royal Navy capital ship.
