E.DA.{Bernard Day - Chassis Design}Ev.{Ivan Evernden - coachwork}Bn.{W.O. Bentley / Mr Barrington} Streamlined Bentley Car. Sg{Arthur F. Sidgreaves - MD}8/E8.11.33 I am in receipt of Hs.{Lord Ernest Hives - Chair}2/MJ.7.11.33 and am glad you have drawn attention to the actual results attained with this car on the road as compared with the forecast given by Ev.{Ivan Evernden - coachwork} as the result of wind tunnel tests! It is certainly very satisfactory to know that the results anticipated have been exactly reproduced and that, therefore, we can place great confidence in wind tunnel tests of this type. Sg.{Arthur F.
