Wind noise and body mounting, proposing a test build on a Bentley chassis.

| -2- The windscreens are all fixed and the car in question in which I rode had, unfortunately, at some past date lost its sunshine roof. As a temporary measure the cover was fitted over the front portion which projected above the roof for a matter of nearly ½ inch. Even with this projection, which had fairly sharp edges, there was a complete lack of wind noise. I should like a further report of this car as regards wind noises as the day in which I rode in it was very sultry with no wind at all. Messrs. Van Vooren will not mount the body as requested in your blue print, i.e. with a certain 5/8" clearance between the bottom side of the rear dumb irons. They bolt the body down solidly on balata packing and they also add another fixing on the rear shackle bar of the chassis. They provide four silent travel fittings with a solid mounting at the rear which we must agree seems altogether wrong, but in practice it seems to work admirably if the car in question is a typical example of this method. I should like to test this method in England and with your permission I should like to construct a standard Bentley in similar fashion and have it panelled in steel with the exception of the four doors and the back flap lid{A. J. Lidsey}, using five silent travel bushes in the construction just for mounting only. Perhaps you will be good enough to let me know if you agree, in which case I would intend fitting it to our next demonstration chassis about which we wrote to you yesterday. ---------oooOooOooo--------- | ||
