HMS London was built as a Devonshire type vessel, all 3 funnels
Between 1938 and 1941 London was reconstructed and resembled a larger Fiji Class afterwards.
I use that source for pics, but also have 14 books on WW2 warships, including Conways & Janes.
I have also spent 9 years wargaming WW2 actions and have 2 different models of HMS London.
