Peter Jackson's attention to detail

At CBR's Oddball Comics Forum, Kong fan Airboy (known in his secret identity as physics professor/pilot/Nash Metropolitan aficionado Dr. Roger Freedman, a member of the notorious San Diego Five-String Mob) informs us of Peter Jackson's meticulous attention to detail in his epic remake:

I was amazed by the whole movie, including the incredible attention to period detail. An example: the biplanes that attack Kong during the climactic scene on the Empire State Building are carefully crafted replicas (in metal and CGI) of correct-for-the-period Curtiss F8C Helldivers, and they're painted in the correct colors of the only U. S. Navy squadron that ever flew these airplanes!
