| BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} 47250 DA{Bernard Day - Chassis Design}2/M28.9.28. 'SS{S. Smith}' RADIATOR. X.7250 X.7260 Herewith we send N.sch.2727 shewing the outline of the front of the radiator as promised in a previous letter. It will be seen that the question of the reduced width has been dealt with by slightly lowering the top tank, and slightly reducing the width of the flat at the top. Both these we think are imperceptible, while the slope of the sides and the radius of the bottom have been maintained standard. It will be noted that we have retained the height of the bonnet hinges previously instructed, so that no difficulty should be experienced with the coachwork already instructed. We think that with this information Derby have all they require to set out the bonnet, and we are not intending to do any more with this. DA.{Bernard Day - Chassis Design} | ||
