Thanks all for the comments and suggestions. I will take all of them into consideration. What I find curious from the actual photographs of Independence is that historically she was cut down to a 54 frigate in 1836 or so. But if you look at the photos of her later in her career she almost looks as if she was built back up while serving as the receiving ship? The top row of windows is probably where the bulwarks were, but then the lower set of windows would likely not have been on a gun deck, but perhaps deeper in the hold? If not, was she in fact a 4 deck ship? I should probably see if I can spring for the plans via US Archives.
