When I was flying around that part of the world, about 6+ years ago, you were reprimanded by all at that airfield for calling it Ha'penny Green.
Including the Air Traffic bods in the tower (which was more of a climbing frame, not really tall enough for a tower).
Even though when talking to Birmingham & all other controllers, everyone knew it as Ha'penny Green.
It was known by all that used it, but based elsewhere, as Wolverhampton Intergalactic Space Port.
Obviously a positive management change.
