It is a bit of an annoyance that the WWII version is best met with Missouri.
And, that none of the quartet are issued in a KW sort of way..
To my mind, they ought be released as Mizzou in "surrender" guise; Iowa in KW fit; NJ in VN guise, and Wisconsin in "last iteration" fitment.
Modelers would still have to cope with the differences between the hulls, but, they could start from a correct era.
