Having been queried a few times re the accuracy of the fore-gun angles on the painting I had commissioned after we discovered the wreck of HMS Exeter back in 2007, thought I'd post the following which shows just what an acute angle the fore guns could train aft on. Schematic from official plans of Exeter: Red dots mark B turrets angle of train, green dots A turrets. As they say, or to paraphrase in this instance, a schematic is worth a thousand words.
It also shows just who Exeter was concerned with / firing on in her last moments, i.e. the southern Jap cruisers, Haguro and Nachi, which were not abeam as portrayed in Capt Gordon's post war drawing.
Also recent historical photos have turned up that seem to confirm that one of Exeters port torpedo warheads 'dislodged' prior to firing and now rests (or did before her recent salvage) under the tubes, as is shown in u/w photos I took.
