On another post, like so many I've seen here in the past, the crowbar on a Spitfire was painted red. No I understand from everyone on this fine site, there is no such thing as a red crowbar. But, it got me thinking, what is the origination of this idea of the red crowbar. How did this develop? I know this is not a burning question for most, but it has piqued my curiosity. Any takers?
