TJ 3906 is an early 1934 Lancashire registered E.W. Wolseley Hornet International used by the Lancashire Constabulary to catch “dangerous drivers”, this image being taken in February 1936. The driver and the photographer worked as a team according to the caption, although it’s not clear if the camera wielding constable sat in the car to take the photographs or was left at the roadside to gather the photographic evidence. Apart from what looks to be an illuminated ‘Police’ sign attached to the car’s front valance, no bells, lights or sirens are apparent.
