Two different sets, one of their original configuration and another set feautring external vent trunks on Turrets 1, 2 and 4, are ready now in 1/350 scale. They will be ready in 1/700 shortly.
For those fans of ships of the class at Pearl Harbor on December 7th, 1941, West Virginia had the original turrets while Maryland had the latter configuration with external vent trunks. Please consult your references to know which configuration is correct for your model.
