Do you know how many doors and what types were used on CA-2?
The forward superstructure will probably be the same as the WWII configuration, but all bets are off as to what was used on the aft superstructure missile house conversion.
Just looking at a few photos of the forward superstructure I saw:
1 quick acting water tight (QAWT) door with the wheel mechanism 26"x66"?
1 eight dog waffle pattern door 26"x66"?
2 eight dog double vertical rib door 26"x66"?
On the aft superstructure I can see several waffle pattern doors, some appear to be the standard 26"x66" opening but at least one is significantly wider. I can't count the dogs in the photos I have. Looks like there may be some shorter than 66" high.
Do you know if the missile house was built of armor plating? If so, the doors will be an entirely different type from the rest of the ship.

When the ships were converted to missile ships the yards just used whatever was laying around for the ordinary 26"x66" doors, especially doors that were removed from the original ship.
Here are the different types of variations I have seen:
Door type: air tight, water tight and armored. Air tight and water tight look pretty much alike.
Number of dogs: 3, 4, 6, 8 and 10.
Dog action: individual, quick acting wheel with dogs on the door, quick acting lever with dogs on the door, quick acting lever with dogs on the door frame.
Surface type: smooth, waffle and dual vertical rib. There are innumerable different waffle patterns!
View port: none, small and large.
I almost forgot to mention the type of watershed over the door (none, curved, pointed) and whether it has a dog wrench beside the door frame.

For my USS Oklahoma City CLG-5 model I discovered 25 different types of water tight and air tight doors on the superstructure - and I think I have just discovered yet another type of air tight door!
The type of door depends upon the position fore/aft and low/high.
The doors on the fore part of the forward superstructure on the main deck were ten dog reinforced water tight doors - to take pounding by green water in heavy seas. Aft on the main deck they were eight dog water tight, mostly individual dogs but with a few quick acting (one wheel type and two different lever types).
On the O1 level the doors were eight dog water tight. The O2 and O3 levels were eight and six dog water tight forward and water or air tight midships. O4 and O5 were mostly eight dog air tight, but it looks like there were some triple hinge three dog air tight doors at the upper levels.
It can be very difficult to figure out the type of door from photos! I have been puzzling over this for ten years.
If you can figure out what you need I have some digitized blueprints for the doors used on Cleveland class cruisers during WWII. However, there must be more than fifty different types of water tight and air tight doors in these blueprints!
Another source of drawings is the DVD of blueprints for the Fletcher class destroyers that was available from the Destroyer History Foundation (looks like they don't offer it any more). It also contained many drawings of stanchions, hand rails, ladders, etc. common to all Navy ships during WWII.

Dang, now I know why the photos I've seen are so confusing. Thanks for the info. BTW I think the movie In Harm's Way was filmed aboard either CA-1 or CA-2 and has some close ups to doors. I will likely limit the number of door types. Thanks Phil
