Thanks all.
Final one for now:
This is NAUTILUS (SS-168) in August of 1943, at the conclusion of a refit period at Mare Island. This refit relocated the forward external torpedo tubes to the more advantageous position at the bow, as on NARWHAL (SS-167). The aft external tubes remained under the aft gun deck, with provisions for reload torpedoes in canisters just aft of the fairwater. NAUTILUS has received a more conventional periscope shear arrangement, with frame supports on the two scopes. She retains the SD air search and SJ surface search antennas. Radio aerial rigging has been modified, with wire antennas running aft.
This is the final configuration of NAUTILUS, with the boat being retired and scrapped in 1945.

On a little side note, am I spotting highlighting shading on your drawings for the first time?
Yes indeed, I finally fell for it... though it makes sense given the strange shapes of a submarine. The earlier Gato/Balao/Tench class drawings use highlighting sparingly as well.
