I'm currently sat here building the Airfix Brewster Buffalo (well, trying to build). Anyway, the instructions says to paint the inside of the cockpit with Humbrol 151. The snag is that Humbrol no longer make colour number 151. So the question is: What colour is 151?
IMHO, it's stupid of Airfix to suggest a paint colour that its parent company no longer makes.
