A Baton Rouge dentist, DR. Ron Kennedy, has spent 30 years building a 1/48th size (O scale) scale model of the WW1 battleship "USS Louisiana". It is mostly brass (wood being only the keel, frame and decking strips) and was detailed from actual blueprints. This model has more detail and better workmanship than any ship model I have ever seen in museums in Washington DC and other public museums made by professionals. Of course they do not spend 30 years in construction.
A major problem may be fitting it into your layout as it is almost 10 feet long!
