Patrick Dyer's eighth book in the 'at work' series takes the reader on a journey with ERF, England's last independent truck manufacturer, between the years 1975 and 1993 with the B, C, CP and E-series trucks that the Sandbach based company produced in the face of overwhelming competition from foreign manufacturers.Apart from the renowned economy, reliability and longevity of the products, the B, C, CP and E-series truck ranges were all linked by the remarkable SP cab, which combined a steel cage with bolt on SMC panels. The system was so revolutionary that ERF patented it. The low cost of design and manufacture allowed it to update and improve its cabs with each series.ERF B, C, CP & E-series at Work draws on over 200 fine photographs from the manufacturer and trucking enthusiasts, which combine with the informative text to tell the remarkable story of these ERF products through some of the most turbulent years of the company's existence.

A wonderful collection of previously unpublished images from the first chairman of the Register ERF Society.
