Bish, that E-2 interior is a can of worms
There was an entire separate set of documents that spelled out the interiors and colors for multi-place aircraft,,,,,,,,,,right down to the color of the seat cushions and even that varied depending on if they were removable floatation devices or not
A very high percentage of Naval modelers use the variations of Dk Gull and Black, with or without some Green or Yellow Zinc Chromate for their S-2, E-2 and S-3 interiors
even the Fujimi and Hasegawa kit instructions differ on what color to paint their model interiors (Fujimi even says to use Tan and Field Grey,,,,,,ack)
