| AJL See me Hs{Lord Ernest Hives - Chair} A.{Mr Adams} FROM TA/EV.{Ivan Evernden - coachwork} C. to W. L. HS.{Lord Ernest Hives - Chair} BONNET SHUTTERS. DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}/W20.10.31. Y1085. Su. pointed out to me at the Salon that our shutters on the whole did not look quite as good as some we have seen, and it was agreed that what we needed was a wider and more well defined gap between the shutter and the bonnet, and that the gap should have rounded edges. These two features will tend to mask any irregularities in the width of the gap between the bonnet and the shutter. We have previously asked Derby to test some shutters having a radius on the edge of the bonnet and the shutter. We would be glad if you would at once make a sample bonnet side panel in the thick material, either .104 or .128, in which the gap is slightly less fine, say 30/1000 average, and with the edges of the bonnet and the shutter radiused.
