The MK-31 directors had MK-3 radar. The MK-28's rarely, if ever, had radar because they were hand cranked and couldn't handle much extra weight. They were upgraded to MK-33's in 1943, and then could carry radar. (A MK-33 was essentially a MK-28 with power drives.)

I don't believe the MK 28 directors carried any radar until 1943 when Mk 4 was added atop them. Also the radar on the Mk 51 directors was Mk 3, long and skinny. Previous Message
As I understand it she had at least 6 and possibly more:
2x Mk.31 main battery (8-in gun) director with Mk.4 range finding radar (one atop bridge structure, one atop secondary conning position)
2x Mk.28 dual purpose secondary battery (5-in/25s) directors, same locations as main battery directors but mounted physically higher
2 Mk.51 AA directors, one for each quad 1.1 position (some ships of the class including New Orleans never got the AA directors for their two stern 1.1 mounts, though tubs for them were installed)

Can someone help me identify what directors she carried. As long as I have built model ships, directors have been a weak point in my understanding.
Thanks,
Rob
