     37.  Camera

       (a)   A G.4B cine-camera is fitted in the leading edge of the
             port plane, near the root end and is operated by the
             cannon-firing button on the control column spade grip,
             a succession of exposures being made during the whole
             time the button is depressed, providing the selector
             switch (5) on the left-hand side of the cockpit is ON.
          
       (b)   A footage indicator and an aperture switch are mounted
             on the wedge plate above the throttle lever.  The switch
             enables either of the two camera apertures to be selected,
             the smaller aperture being used for sunny weather.
             A stowage clip is provided to receive the electrical
             cable (13) when the indicator and switch are not fitted.
