Re Coronation Vibrations.

TEB6/123412.

Members of the Tech. Committee 24.4.12.

With reference to the suggestion that the brake drum should be made more symmetrical, Mr Royce says "that this lack of symmetry is the reason why the torsional vibrations affect the car, but this seems of little importance as long as we can get rid of the cause of the vibrations."

To. Eugene Schelbein.
