Dolphin Control and Pump Room

Control Room
In the center above the helm wheel is the rudder angle indicator, flanked on both sides by the engine order telegraphs. The lever on the vertical shaft was used to engage/disengage the control room helm from the conning tower and bridge helm. Which helm would have been the primary station for submerged operations? We would lean towards the conning tower, but that opinion might be flavored by what was done in combat in WWII and may not necessarily reflect pre-war 1930's practice.
Large levers next to helm are for switching from normal hydraulic to hand hydraulic. In hand hydraulic you spun the wheel to develop hydraulic pressure and this was a very laborious process.
Oval hatch in deck next to helm most likely leads to a store room. Note speaking tube to conning tower above the helm.
