Mr. Jack is correct first, it is the South Dakota. As Terry stated, the 4 twin 5" gun mounts on either side of the superstructure is the giveaway, the remaining 3 ships of the class had 5 mounts. The difference is that the South Dakota was built to function as a flagship and and extra space was needed for the extra living spaces and and admnistrative spaces needed for the fleet admiral, necessitating the removal of one mount per side, as Terry alluded to.

Mr Jack, it is your turn. If you can't post a pic, let us know and Terry can take it.
