very nice pics thyro!
in that second picture down, the bridge pic, the guy on the left is the lookout and the guy on the right is the Junior OOD (from 6 guys to 2 in just 40 years) because the OOd is BELOWDECKS in the Control Room.
EDIT: but then, with a bald spot like that on the JOOD, he might be the OOD, no offense to balding ppl, of course
note the flashlight on the holster on the windscreen, used when one can't see the compass in the dark, and the sticky antenna, used only (and still with a lot of caution) on the surface. The windscreen is hinged and folded up and taken below when its time to dive, and i think its against regulations for the lookout to sit in the bridge, like the photographer is also doing
