The erstwhile National Bus Company was the largest bus company in the world and like any large organisation, it required auxiliary vehicles to support its core activities.

Formed of around thirty-six local constituent companies and the ‘NATIONAL’ Central Activities Group, each company had its own Service Vehicle fleet to support its operations, varying from Heavy Vehicle Recovery to Driver Training and every other facet to keep the fleet operational. Well photographed and documented were the former PSV conversions, Driver trainers, Tree loppers or Towing buses, as these were based on a bus and attracted the attention of photographers and enthusiasts. In an era when film was precious, the commercial vehicles owned by the NBC were often ignored, making photographs very rare.

In this second volume we look a more examples used by the NBC between 1972 and its demise in 1986.
