It was pointed out by me at Mulliners that the wind screens supplied for the Goshawk bodies and others were not rigid enough in their fixing. I believe the fault has occurred owing to some part of the framework used to support the wind screen, being in torsion, which seems to cause greater flexibility than when the parts are in pure bending. The fittings by Park Ward & Co., on 6.EX were very satisfactory, the wind screen being quite rigidly held up. The connection however between the hood and the wind screen in his particular instance was very defective, and a cause of much rattle, which could and must be avoided. R.{Sir Henry Royce} | ||
