Ok, pay attention...cause here's what you need to do KGV in mid-1941...trouble is, the KGV kit from Tamiya represents the ship as she appeared in 1945, not 1941. Major differences not only in the weapons layout, but lots of platform changes as well.
Your best bet would be to get ahold of a Prince of Wales kit and make the necessary changes to her instead. It'll be alot less work....but anyway, here's what you need to do.
She carried Type 284 radar on her fire control director, as well as Type 279 Air Warning radars, one on each topmast. She also carried a HF/DF coil on her main topmast. In early 1941 she received Type 271 radar surface search radar (the lantern) and was carried between the forward high angle directors, in the former lookout position.
She carried 4 Mk VI 8 barrel pom-poms, abreast of the forward funnel and another slighly forward and lower, on each side, and she didn't get 20mms until December of '41, so leave them off. She had 4 UP projectors, one on B turret, 2 on Y turret, and one located on the quarterdeck.
There was no camouflage, she was painted Medium Gray 507B overall, and her decks were natural teak.
