Matt Black -- BW Key

One of the last vestiges of the BW Canal era is consigned to history says Hugh Baton. The "BW Key" will be replaced over the next 3 months with a new high security version. The "AV key" will cost £100 and only be available from AV offices or by post. The reason for this change is that every Tom, Dick or Harry could get hold of a BW key for around a tenner said Hugh and gain access to AV facilities
