Mr Royce was anxious for you to try the effects of louvres in the bonnet of the 40/50 and Goshawk respectively, with the object of improving the cooling effect on the radiator. R's ideas were based upon the fact that he considered we had the largest radiator we could fit which ought to be sufficient for the purpose, and if it was not it was more a question of making adequate provision for getting the hot air away than it was for increasing cooling surface.
