C. to R.{Sir Henry Royce} WOR.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} re. BOOMING OF BODIES. X.634. X.3805. With a view to correctly understanding the various reports which have been received on booming of bodies, and the apparent perfection of Bentley products, we would be glad if you could give us a description of the coachwork as fitted to the cars which have been tried by yourselves, that is to say, type of body- 4. or 6 seater - whether roof is fixed or not, and whether it is panelled or fabric body, also whether the rear seats were in front of the rear axle. The writer is endeavouring to get a trial run in a Bentley with a 6 seater Pullman limousine body on it so that the tests may be comparable with those on our own car. We are shortly publishing a thesis on booming from all its aspects indicating experimental research which we suggest could be carried out with advantage, and we shall attempt to explain the apparent perfection of the Bentley, not with any pre-conceived prejudice either for or against it.
