Your questions made me go back and look at the "Lady Lexi"'s history. True, both she and her sister ship the Saratoga were initially laid down as Battlecruisers, but due to treaty, were scrapped as such. Hence, the Lexi was built as an aircraft carrier, retaining the battlecruisers hull. Her stack was a new idea for the Navy designers and I suppose, as a first crack, she was built rather large to accomodate her stacks. I got myself confused with the USS Ranger CV-4 which was the very first Navy aircraft carrier to be built from the keel up as such. She was smaller and originally was not going to have an island. Her stacks, as I mentioned before were much like the Langley's, pivoting on both sides for this ship. Later classes went for the island stack arraigment for more modern carriers. Funny how it all evolves. I have mounted my first support structure, whiich is the "key" support that all the others will reference to for placement along the hull fore and aft. Pics soon. Dennis
