Just thought a mention a major environmental mapping oversight. The mirrors on the P38's inside engine nacelles don't reflect. Would be a nice touch.
You look around the internet and about half the WW2 pictures show the polished disk on olive drab fighters. You can assume bare metal fighters it will show as a refelction. And I see the disk included on at least two restored P38 in overall green paint.This means at the least the all metal skins in the game should show the gear as some king of reflection going up and down. I suppose in refrence to the two restored P38, the professional restorers are not WW2 P38 historians of your caliber Ack Ack.
