Shipbucket Standard grey example
Measure 32/21D scheme in 1944, this is the ship as it appeared with Gen. MacArthur onboard before Leyte Gulf. By the end of the war, the surviving Brooklyns had their bridges reduced to reflect war experience. More light AA has been added. It's also interesting to note that the ranging radar on the main battery Mk.34 directors is different fore and aft. This is not an error; several photos of the Nashville have confirmed it. I'm not sure why this is the case.
Camouflage is Measure 32 design 21D, a 5-L Light Gray base with 5-O Ocean Gray splinters.
Have to thank DarthPanda here, his drawing of the oversized Brooklyn helped me decipher what was going on with the bridge superstructure. This is the late-war style that was then sold to the South Americans, so if anyone wants a slimmed down version (no camo, railing, rigging, etc), just ask. That way conversion to Belgrano or Capitan Prat won't be very difficult.
