BAP 886K A MG B GT police car. Currently being privately preserved, this 1971 example is displaying an optional ‘wide load’ sign for escorting large vehicles. This type of car was used for traffic policing duties, but didn’t really have enough carrying capacity.
The rear view of the same car. Notice the illuminable stop sign on the rear bumper. When not on display, the police sign and blue light are removed to stay legal on the roads.
