Storytime! After entering service this airplane experienced a mishap, someone rammed into the cockpit door and damaged it to the point of needing to be replaced. But being wartime there wasn't enough time to bother painting over it again, so it went on as it was. Or that's my excuse for accidentally masking off the wrong part of the door making the colors be reversed. Doh! However I'm happy with the happy mistake, adds a bit of character!
