Nice variation!
The main hull is 90% FS 36622 (Federal Standard color codes), with 10% flat white. The semi-light portions should be FS 36622, The med-dark sections I used 90% 36440 Flat Gull Gray and 10% white, and for the dark (which isn't black) I used FS 36440 + black + DK Panzer Gray + wood until I got it right.
The main colors were listed in the instructions, from what I remember, and I got most of the shades from there, as well as screen pauses (95- before "screen caps") comparing the tones with the FS colors I had.
I'll try and post pics of the "map" I drew out, that helped me with that painting nightmare.
