There are two ships in this download:
USS_Nevada_1941_LOD, which only has the 0.5 inch AA guns armed.
USS_Oklahoma_1941_LOD, which only has the 0.5 inch AA guns armed.
There are two .dp files for each ship:
USS_Nevada_1941_LOD, which has the 3 inch and 0.5 inch AA guns armed.
USS_Nevada_1941_LOD_No Guns, which only has the 0.5 inch AA guns armed.
USS_Oklahoma_1941_LOD, which has the 3 inch and 0.5 inch AA guns armed.
USS_Oklahoma_1941_LOD_No Guns, which only has the 0.5 inch AA guns armed.
The texture file USN_BB is unique to each ship.
The turret tops are the appropriate color.
Cheers,
Stuart
