As Richard P said - what kit are you planning to use? The kits of WARSPITE in 350th scale depict her after her major reconstruction in the 1930's, and during the Second World War. That being said, an excellent starting point would be to acquire a copy of "The Anatomy of the Ship - The Battleship WARSPITE", and the Shiprcraft series on the QUEEN ELIZABETH Class Battleships. Both are excellent references.
Hope this helps.
