Found a new image of the main armament, as it looks today....there is very little marine growth for a wreck this old. You can see one of the turret doors open....very eerie.
Based on the picture of the anchor, this seems to conform both the forward section (with anchor, of course) and aft sections were located. Survivors said that she broke in two forward of the bow turrets, so all three turrets are attached to the aft section.
