Thanks for your input Brett, much appreciated! But re your suggestion above, is that doable on-line(?), as given that I live on the other side of the world, literally about as far from Oz as you can get before you hit the North Pole, it will be very difficult for me in person.Brett Morrow wrote:The possibility exists that the actual boilers/boiler deck are not shown on the overhead plan. It is also possible that what Tracy has pointed out may be the fan assemblies in the fan room above. While it is likely the boiler room plan remained as originally designed for a 3 funnel cruiser your first mission would be to ascertain if that was the case. The profile plan `as designed` matches that of a Kent class, HMAS Australia which also shows the boilers in the same positions of the funnel uptakes, so your green dots may actually show the boiler foundations. An overlay of the overhead lower deck plan matches the position of the boilers shown on the profile. You could check Australia`s ships book No 4 at NAA Canberra which has the boiler reports and may possibly answer your question relating to A and B sets.
Be that as it may, below a collage of the three deck levels above / below where BR is located from the 'as designed' plans. As can see still no indication of exactly where they are. And my understanding is there are no plans of her 'as actually built' (as opposed to 'as designed'), nor aware of any changes to BR's at any time. Of course, that doesn't mean there weren't any.
