Yes, sadly I agree about janes and asume there is an element of time saving versus known information at the time of compiling the information. Though there are some evil mistakes such as showing the Invincible diagrams for the Indefatigable class battle cruisers. I take on board that the former was a direct inspiration for the latter, but the turret and superstructure layout is quite different.
Still, the titbits of information are inspiring, and seeing battleships in one section appear again in another as converted for a lowlier task such as HMS London who was converted into a Mine layer and painted in razzledazzle also interest me!
Amphitrite was also converted to such a role. (Cruiser)
Thankyou for all this assistance. I will diligently continue looking for information and build up a dossier (assuming someone does not produce a kit!)
