Francis Webb is an interesting person and while we are waiting for You Know What, a discussion can be fun. He was a talented dictator and to please our middle class,wellfare state way of thinking , Nock/Talbot paint a picture of LNWR being saved from disgrace by having Whale and Bowen Coke. Webb recognized around 1900 that the Jumbo,Teutonic Greater Brittain line was a dead end. In a short time Alfred the great and Bill Baileys were designed and built. Before he resigned Alfred Valve gear was changed to four Joys from having only two inside. The maybe superfluous/useless central bearing on crankshaft was unchanged. Whale takes over and his Precursor/King George class is nothing but a simplified Benbow Same story for Bill Baileys to Experiment/Prince of Wales transformation. Webb was behind LNWR locomotives to the bitter end.
