| X1085. To RHC. {R. H. Coverley - Production Engineer} From Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 11/MJ.13.4.31. NEW VENTILATED BONNET. X1085. x1260. You will remember that we mentioned to you the other day the new ventilated bonnet shutters for the 40/50. We asked you to make a set for 27-EX. As we are just about to run a cooling test on Brooklands with 19-EX. we think it would be a good chance for us to test out the efficiency of these new ventilators. For the purpose of test we should like three shutters equally spaced per bonnet side, and should be obliged if you will do what you can to let us have this.
