I can't vouch for the truth of this but relate it as told to me.
Gutersloh about 2 months before handover to the Army.
At the guardroom a car arrives with Army Lt Col at the wheel.
Lt Col enquiries of gate guard, "Where's Princess Royal Barracks".
Guard responds, "Dunno, sir. Never heard of that one".
Lt Col. "Don't you know that this place will be Princess Royal Barracks in 2 months?"
Guard. "Really sir? Well, best you come back then, sir."
