SbCommittee have a good thread on sound heads and exhaust ports (two threads really, but you can find the other):

Fantastic! Hope you have a great time, but also hope you get some great shots and can share them with us.... ;D

Would it be too much to ask if we all created a list of bare minimum shots we're dying for? Close up stuff? We'll even buy electrons for your camera... ;)

We'll work you to the bone, man!

DECK - close ups and medium shots of DECK (metal and wood if she had it)
Conning Tower - masts, radar, hatches, etc.

I'm sure others will have ideas too!

Thats a big 10-4 on the conning tower since I'll be doing a scratch on it.

I made my trip and got some good shots, my need to make another trip. USS. Silversides had a partial wood main deck and the conning tower had a wood deck, I thought she had metal all the way around.

I thought she did too, based on a 1941 December photo. It was possible to FROM all wood TO metal (repair), but unlikely to go from metal to wood. Highly unlikely. I will rack that source and see what I can find out. Usually museum boats get only semi-accurized and to post war standards, very odd, thanks for the info!

Ahhhh, brain working again. It's been so long (about the decks, not my brain doing work) that i had forgotten. In my Gato deck research notes, I labelled "wood deck" as "wood entire deck"; and "metal" as "wood /metal/wood" (bow and stern metal, main midships wood).

SO, the Silversides in my terminology is a "metal" deck boat :metal/wood/metal

Hopefully I wasn't confusing or misleading...

AAAHHH! My brain is working again also, I remember reading that in your research. Must have forgotten about it, sorry.

One question for all of our fine modellers. Does any one have pics of the bottom of a Gato? I'm placing the openings for the flood vents, free access, and access doors and transducer heads and I have no idea what they look like. I got the early war stencils from Nautilus but I was thinking that they can't just be holes in the outter hull....can they.

Also, I have pics of the exhust ports on the Silversides but only on one side. Would the exhusts been on both sides? And would they have mirrored each other?

hull opening on the bottom - Navpers has a lot of good info. I have template from a gent at SubCommittee, email me for a PDF (amp@rokket.biz). That's a lot like the stencils, but there is some disagreement over what's closer. Some were holes, some were flush hatches (not true hatches), etc.As for the pix, Navpers  and maybe Mike K. Mike? - also same for exhaust. I would think the same, but I've got nothing but VIIC and basic rough logic to get to that conclusion.

   Flood Ports were just holes. Some round, some oval, some trapezoid, it varies from class to class and, sometimes, boat to boat. But none had gratings.
   Flood Valves were usually round. On a model, (when closed) they'd appear as round, recessed, blanked off holes, since they opened inward. Some Flood Valves, like the Negative and Safety Tank Flood Valves, were recessed, and would look like Flood Ports.
   "The Fleet Type Submarine", put out by www.Periscopefilm.com, should answer most, if not all, questions.

   As far as the exhaust ports, I remember them as oval shaped. The shape forced the gases to blow towards the stern. I know that Pampanito, Cobia, Silversides, etc all have round ports. But, were they always round, or is it the result of many years of upkeep, and round is easier (and cheaper) to fabricate, than oval? If I ever run across a picture dating back to the old days, that clearly shows the ports, I'll accept that.
   Until then, go with your gut feeling. If I find such a picture, I'll send it out.
