Looks damn good.
I like the weathering you've perfected so well.
On the color image it looks like E2*S has red on the gunports (I definitely see a hint of red!), but not on any of the others. On E2*C it almost looks like a continuation of the BMF from under the invasion stripes, and on E2*A and E2*H it almost looks like it's black.
I think you could make black, red, or silver and still be right depending on which photo you look at (heh heh)
I say don't sweat the gunports. If you think they're red, do them red. One part about skins is interpreting your sources. If you discover more info later, just change that layer and resubmit.
