Nothing definitive standing out to me, only clue could be the rafts on the side of the turret. These seem smaller than the one that Helena had and similar in size to the one St Louis carried in June of 41. Post 12/7/41 Helena image seems to show a larger raft on the turret side. That is a small and easily changed detail but it’s what has caught my eye so far. Images of this era are rare and detailed images of this area are even rarer still.
