If I may ask Fontessa, what book did the diagrams in post #2 come from? Were they from one of the Grand Prix Shuppan(?) books?
Yes, Yes. The book is 軍艦メカニズム図鑑 / 日本の巡洋艦 森恒英 (グランプリ出版) Japanese Cruisers / Warship Mechanism Picture Book Written by Mori Tsunehide (Grand Prix Publishing) It was published in 1993. All the illustrations in this book ware handwritten by Mori, himself. His second work is 軍艦メカニズム図鑑 / 日本の駆逐艦 森恒英 (グランプリ出版) Japanese Destroyers / Warship Mechanism Picture Book Written by Mori Tsunehide (Grand Prix Publishing) published in 1995. I used pictures of destroyer funnels from this book. I was hoping for his battleship, aircraft carrier books, but he died before my wish was fulfilled, unfortunately.

Re Haguro's, so her top two white bands seem to meld / join into being only one wode one for front half of funnel, correct?
Let me talk about the funnels. The third picture shows two Treaty-type Heavy Cruisers - HMS Cumberland and IJN Myoko. Comparing the two ships, you will notice that the Myoko bridge structure was located rearward, giving her the space for the third turret. You can see why this was possible by looking at the third picture. The upper is Kitakami and the lower is Myoko. I couldn't get a picture of Cumberland, so I used Kitakami, which seems to have the same structure, instead. Both Cumberland and Myoko had 3 boiler sets and 3 funnels. Cumberland connected boiler set and funnel straight. On the other hand, Myoko devised the way to connect boiler set and funnel. The first funnel bent significantly backwards. IJN called it 誘導煙突 guided funnel. Then it was integrated with the slightly sloping second funnel. IJN called 結合煙突 combined funnel. The fifth picture shows the bridge structure, which could be located rearward by straddling the first funnel.
I used Mori’s handwritten pictures from his book in my fourth and fifth pictures.
Comparing Myoko and Cumberland, I feel that Myoko is more beautiful as a Japanese. But this does not mean that Myoko was superior to Cumberland. Myoko strengthened her armament against the United States and Britain, which won by number. Treaty-type heavy cruisers with limited displacement cannot satisfy all items. She had to sacrifice something. Myoko sacrificed range and habitability. The Royal Navy's mission was to protect the lengthy sea lanes and guard the colonies. The British colony located in hot areas, so Cumberland also had a great range and good habitability. Myoko Class Ashigara participated in the ceremony to commemorate the crowning of George VI on May 20, 1937. A British naval officer who visited her said, "I saw a warship for the first time today. We were on a hotel ship." It was a famous story that he sarcastic about Japan ship’s poor habitability. After all, the ship meets the requirements of her own navy was an "excellent ship".

) given outline of wreck and depth to highest point possibly upright, but if so must be nearly burried to her deck level in the muddy sea bottom in that area. Not sure if I can access the side scan image/s any longer, as group has broken up, boat sold and ex owner / skipper now driving a tug in Darwin. I'll see if I can get, but don't hold your breath as skipper may no longer have, or currently not easy access to.

And while I would love to see the image, I completely understand if you can no longer gain access to it.
