I have just been on a web site called "The Ford Flathead v8 Site" in the "engine specifications", "the middle years", at the bottom of the page, it says; "Original paint colours."
Ford and Mercury through 1940 were dark green.
Ford continued the colour until 1942
Mercury used a dark blue colour from 1941 through to 1948
Post war war Ford were dark blue to 1948.
Ford truck engines were generally the same as cars.
My observations;
There is no mention of Ford colour from 1942.
There was obviously some variations in truck engine colour.
There are no specific comments about military engines.
