For what it is worth the correct RAF Dark Green , used in the early war years, is Federal Standard 595 Color FS 34096
I'd be interested to know how well the paint used by Morgan matches!!
It is also a standard BSI colour as well, but I thought the FS would be more use in the USA...
The colour fades in strong sunlight and goes more earthy.
