I'm interested to see the revised early versions. I think it would be pretty cool to see the ship with 1.1" quads, early radars, etc, and then of course a penultimate "1945" fit as you've drawn. A 1944 version with one of the Measure 32 camouflage patterns would be great too!
For what's worth the first drawing, the one based on the 1940-1941 model and plan (which I wanted to link, but cannot, since Navsource is down) sports CXAM-1, Mk.3 Mod.2 radar on main gun director (with plan showing it only on top of the fore director, so I might remove the one aft) and Mk.4 for the 5-inch. Plus there is an unidentified radar mounted above the n°2 funnell which I've failed to identify, but appeared, according to the model and the plan, to be planar like the CXAM and have around the same dimensions of the Mk.4 or Mk.12 ones for the DP guns.
It would be cool to see "Montana" as it would appear throughout the entire war - starting with an early version with Measure 12 modified, then a Measure 21 version (all Navy Blue), Measure 32, then finally Measure 22 and so on. You've unfortunately ignited a spark of Aspergers inside me and I can tell this project will end up consuming some of my time as well!
Strictly speaking, the Montanas would have started beign commissioned at best by the first half of 1945, so that might have been too late even for Measure 32 scheme. Yet this eventually not forbid us to "go overboard"
. For now I'll focus on the 1941/42/43 models and the 1945-1948 fits, but this does not negate the possibility of adding extra drawings later.
Unfortunately after 1945/6 you're on your own as my expertise drops off phenomenally quickly. But I have to admit this has me considering putting to paper some of my ideas around an alternate history invasion of Japan, where for some reason the war ends up dragging on until 1948 or so, during which time all the Alaskas, Montanas, and Iowas are completed as planned.
No problem Colo, I have no particular versions of the Montana planned after the 1948 one, and I already did some "forget-about-the-budget" missile conversions posted in another thread featured in the "personal designs" section (crowned by an Iowa-ish 1985 refit).
