D-Boy:
I have found Atago 1944 (Amagi class) in Navy Yard 17 and Hiraga class X (Kongo Replacement) in Navy Yard 16.
The pictures are mostly the same but are in many cases in different sizes. These are the only issues of Navy Yard I have so I do not know if they are more duplicates. I have put this issues in the list below. Feel free to make completions if you ór others know more duplicates.
The english title of the real ships book are
The battleships and Battlecruisers of the Hachi-Hachi fleet , by Kojinsha
See here:
http://www.hlj.com/product/KJS81504/NavI do not how to post a link but I attached the adress as of today.
This book is highly recommended, with its large amount of plans in 1:700 scale both on double/quadrupleturreted versions, several colour pages of the ships as how they would have looked.
Also plans of details.
This book has been mentioned before by others and myself.
Can you specify what you would like to know about this book
Back to the book about finished ships in 1:700
It is some general pages with info and pictures about the real ships also
Following 1:700 ships are covered, about 2-4 pages each in general, :
Nagato 1920 (Conv Aoshima)
Nagato 1933 (Aoshima)
Nagato 1944 (Aoshima)
Mutsu variation plan (5 turreted) Conv Aoshima
Mutsu 1937 (Fujimi)
Mutsu 1941 (Fujimi)
Tosa (Fullscratch)
Amagi (Fujimi)
Takao (early vers, combined funnel) Conv Amagi Fujimi
Akagi 1941, Bent forefunnel as Nagato and second funnel still there Otherwise pagoda structure etc, Conv Fujimi
Atago 1944 (single funnel as Nagato of similar year) Conv Fujimi (Navy Yard 17)
Kii 1920s twin raked funnels, secondary turrets 4 twin each side as in KGV in different levels Conv Fujimi
Suruga 1920s 4xtriple turrets, 4 twin secondary turrets each side, same level, Single funnel listed under Kiiclass, Conv Fujimi
13 class Takachiho 1920s Early4xtriple turrets 16 inch casemated sec turrets Full scratch
13 class Fuji 1920s 8x18 twin turrets sec casemates Full scratch
13 class Shirane 1941 8x18 Twins, sec in casemates and modern pagodastructure, aircraft facilities Full scratch
This last ship I like a lot, strangely the IHP kit seems not have been used for the 13 class ships. At least the hull would help a lot.
Hiraga Design X 2x3 2x2 16 inch guns Full scratch (Navy Yard 16)
A little about US counterparts (2 pages each):
USS Maryland (Pit Road)
USS South Dakota 4x3 triple Turrets (IHP resin kit)
USS Lexington as battlecruiser 3 pages Full scratch
There are some pictures of other models of the same era so the book contains more info than this , but this is the main subjects. Also other info between the models. 96 numbered pages so it is about the same size as the Navy Yard, or actually a few pages less than my two issues of NY.
