Thanks all.
While I wait (seemingly interminably) on the FDD plans of CL-97 to arrive, I took a swing at some earlier versions of CL-54. I'm planning to also do the 10/44 version with the Measure 32 camouflage.
First in 1942, with an especially difficult Measure 12 (modified) scheme that was very hard to find references for:
After the Mare Island refit, December 1943-January 1944. 40mm Bofors, SC-2 air search set on the foremast, and a revised pilot house structure. The classic Measure 21 all-over navy blue that I love so much!
