A slightly higher view of the forward control room bulkhead. The engine order telegraph transmitters for port (red) and starboard side (green) are visible. To their right is the red and green rudder angle indicator/transmitter. Toward the top left is the projector for the magnetic compass (a backup to the gyrocompass), which is housed externally just forward of the conning tower. The large black wheel near the right edge of the photo is the flood valve shaft for the starboard negative buoyancy tank. (Caption courtesy of Matt Hamacher)
