X7741 X7560 [Handwritten] With further reference to the above, it is understood that single pole fittings for interior illumination of bodies etc are practically unobtainable. Also that there is a danger of coach-builders running bare earthing wires through the upholstery of cars, introducing danger of fire. In view of this R.{Sir Henry Royce} agrees that twin wiring should be retained for accessories, and that a suitable earthing stud be provided on the dash near to the accessory distribution board.
