Bullethead I stand corrected on the tripod tops.
The Mark of 5.25's the Prince of Wales class carried was manually loaded, that caliber calculated to be the largest where manual loading was practical. The battleship Vanguard, completed after the war, carried meachanically loading 5.25 mounts which doubled the rate of fire, to 18 rounds per minute. It is interesting to speculate how P.O.W. would have fared in her encounter with the Japanese bombers if her batteries had been pumping out a hundred extra, big, long range shells each minute.
