This is an FG-1D Corsair of VBF-83, USS Essex (CV-9), May 1945. Markings are from Starfighter Decals sheet 72-143. The geometric shapes on the wings and tail were known as “G markings” and were used to identify the air groups of the parent carrier. They were used during the first half on 1945. However, these proved difficult to describe over the radio, and were soon replaced with letters.
