sorry for huge image...stumbled acros this one doing some receartch....

WTF!!

**ANOTHER DESIGN IDEA**







IJN ROX!!!

lmao

Karle you like what if`s...above should be a challenge ......have no words...its extremly ugly cool awsome stupid design....but it stil wins in pure coolness lmao....that thing have more guns than the entire IJN combined.....

Indeed I like "what ifs." The ones that you posted are pure insanity, and therefore doable in my mind. But I won´t make anything bigger than my H-44.

[peabody]

I have not had much time, but I did do these for the bridge. From images I found on the internet. I still need to put the lettering for the speeds on the telegraph.



BTW, does anyone actually have an pictures of the bridge of any of these ships? I have found almost nothing on the net. I did find equipment but not an actual picture of the bridge. Of course now that I have done these maybe I don't want to see a picture, they are probably all wrong, but they are from actual ships, and they add atmosphere.

oh my god this battleships looks like a daughter from fuso yamashiro nagato and kongo

[spike12]

What were they smoking when they came up with those designs and where can I score some.

WOWSER! that looks stunning

Looking through all my books. Unfortently The Japanese wasnt the most photographic people.

My books are mostly about the Japanese cruisers and heavy cruisers, i browse through them this evening to se if there are any pictures. Atleast a schematic that show the bridge layout.

Well back to button coordinates and photoshop...

Been looking at my books. Have to admit that around 85% of them are about the Takao class, yes i know im a fanatic.

Have not found any photos from inside the bridge, and here we run into a problem.

Fot the Takao you se 3 greenhouses, guess what, the helm is not on any of them. Its actualy two floors below the lowest greenhouse.

First greenhouse is the obervasion deck, where all the huge bino`s are locatet. I have an awsome cut in half superstructure schematic of the Takao class. Im going to post my findings, but i have to make sure i kinda cut away some bits etc to make sure i dont get copyrazed...

Might do that this evening are latest tomorow noon

Here are a few titles from my book colection

Anatomy of the ship The heavy cruiser Takao
Imperial Japanese navy heavy cruisers 1941-45
The heavy cruiser Takao 1927-1937
Japanese heavy cruisers of WW2
Pictorial-IJN heavy cruiser Takao

So most info on the Takao i do have, but just not internal photographs of the command decks...wierd...

Found this one. Not a cruiser, but atleast some Helm stuf

abit more early, but here is one from the navigation bridge of the pre dreadnaught Minkaza (museum ship)
