WW II US boats didn't have snorkles. The Germans did and I really don't know the piping or line up for them.

The Snorkle boat I was on sucked air into the main induction piping and ran it aft to the Fwd and Aft enginerooms. There the enginroom inboard inducton valves were opened, (32 turns done manually), these were 30" ID pipes. Air was still pulled from other places in the boat if the WTD's were still open.

No AMR's on a smoke boat just Fwd and Aft Engine rooms. Nuc I was on we had an AMS, later to be renamed an AMR. This was aft of the Reactor compartment. The "Air House" (now also called an AMR) was at the aft end of the torpedoroom. This is where the CO2 scrubber was and the COH2 burner and HiPAC's.

688?

Picture a W/T bulkhead with reactor shielding behind it about midway down the hull, W/T door into a small tunnel going aft at the extreme stbd side, halfway "up" the hull (at the 3:00 oclock position, facing fwd.) Reactor is behind the shield walls around the tunnel on the ship's CL above the keel, but (unlike 637's) there's no equipment in the tunnel.

Engineroom aft, maneuvering on the fwd upper level of the ER.

Fwd, the hull is three levels: On the lowest level, from fwd to aft, torpedo room, then a 8 man bunkroom, then AMR where the diesel, O2 generator, and refrigerators, etc. were. A-gang territory. Batteries below the torpedo room, SK storeroom fwd of the torpedo control panel.

Mid-levels is almost entirely crew space: bunkrooms, heads, chiefs quarters, 4" launcher (doc's office is between the launcher), wardroom, officers bunks, reefers, crew's mess, kitchen, etc. Torpedoes get loaded down the middle access, which hinges up to make the same kind of hydraulic slide you're used to seeing.

Upper level is sonar eqpt room fwd, sonar space, and control room, CO/XO, radio room, fan room. Little bitty Nav/ET space aft of control that had our SINS and gyro. 400 Hz too, I think. Next to the ladder the other guys dropped that gyro down.

No other W/T hatch fwd, except the one going to the sonar sphere.

You're right: Snorkels got loaded with the Guppy conversions in the late 40's.

Topside gear got removed, covered up, or streamlined as well.
