EDIT#1: Right, I shouldn't have looked for pics (LOL...?) for the other ships Indiana (BB58) and Massachusetts (BB59) - MaritimeQuest, Navsource and/or History.Navy.Mil ... I noticed that their boat cranes are present during 1942/43. Realizing Alabama being the last ship of the class, I cannot get over this difference and will have a model for those two (with boats and cranes... worse, have a different model? we'll see)... but will have to do it *after* I'm done with the lead ship USS South Dakota (BB57) with only 8x 5"/38cals...

5-2-12 #1: The BB57 South Dakota is done. Photos of her during her shakedown cruise in 1942 are widely known, but I based her appearance on Photo# 80-G-36088, late 1942 according to the caption (during the Guadalcanal campaign/Battle for Sta. Cruz Islands). This link will take you to her (BB57 South Dakota) entry in the National Historical Center.
Additionaly, this link directs you to BB60 Alabama's Battleship Photo Archive over at NavSource Online
5-2-12 #2: Next up BB58 Indiana. Modded the Alabama sculpt to coincide with the photographs, please see this link for some very good (large-ish) pics; focusing on the year 1942 (render below BB58)
5-6-12: Done with the BB59 Massachusetts. As said earlier, modded SoDak sculpt with the additional pair of dual 5"/38s. Platforms to correspond, and the addition (subtraction?) of an indent on the mid-portside of the forecastle, forward of the A turret...
