Eric Platford - Chief Quality Engineer} E.1/HP.25.7.33. Bentley Chassis - Two note Horn. It is not possible to arrange for two distinct notes to be given by the horn by graduated pressure on the knob on the Bentley chassis as the connection is made by a wire passing up the centre of the steering column, which only permits of one switch position.
