Looks like the model was commissioned in May 14, 1945.
May 14, 1945: You won’t find the USS Fighting Lady on any official rolls of Navy fighting vessels. But 70 years ago today, the aircraft carrier had her very own commissioning ceremony. As reported in the Shipworker (on May 22nd), the Fighting Lady was a 103-foot scale model of an Essex class carrier built by workers at the Brooklyn Navy Yard. Located in the Lower Plaza of Rockefeller Center (where the ice rick usually is), the public could visit her by buying a War Bond and she was used as the setting for several bond drive events. The Fighting Lady was the fictional name of the ship in the self-titled 1944 war film about carrier operations filmed aboard the USS Yorktown (CV-10).
is it possibly at the Brooklyn Navy Yard Center?
