Sorry I don't know what sort of proof you require, I can quote you the book it came from. It was from the Images of England series entitled "Erdington". You could get yourself a copy for £11.99 I believe mine cost, because I'm sorry but I have loaned my copy of the book to a friend at the moment. If you can wait until he returns it I will scan the whole page for you.
Though I can't see the point its only a game after all, but never let it be said that I left anybody in doubt.
