This is the Glover Webb APV (Armoured Patrol Vehicle) that was replaced by CAV100 (Snatch).
Asset Code 1722-4100 Truck, Armoured Patrol, 4x4, Land Rover 110 (V8), Heavy Duty
Availability of spares would not be helped by Glover Webb being taken over by Alvis & then the factory on the Hamble was shut down & Tactica production with it.
