This is a model of AGSS-555 and it's spot on. I cannot find one photo showing "Dolphin's" port side as clearly as this. It's always taken from the Starboard side. Here you can see the ladder rungs on the portside. On the bridge shows the railing and bench for watch standers. In the rear/aft end (right side) you can see a white round "surface" radar.
On the forward (left) side of the bridge you can see "DOLPHIN's" own unique sonar equimpment. This picture was provided by http://www.fxmodels.com/agss-555.shtml
