This image shows the van used by the Radio Research Section of the National Physical Laboratories at Ditton Park as a mobile radio receiver station. It is a KX 50 Flatnose Morris with Eccles Caravan body. The image was taken by Arnold Wilkins, who would later use this van to demonstrated radar in 1935's Daventry Experiment.
