I definitely remember the Fraser Imps. I also remember watching them cornering on three wheels around Druids. I lived in Maidstone and attended Brands on a regular basis. 
Also I worked at Rootes in Maidstone from 1966 until 1972. On a couple of occasions they bought one into the body shop for repairs after having mishaps on the circuit.
By the way, you have the colour correct. The front panel was white and not blue as the first photo.
