| γ 605 To By.{R.W. Bailey - Chief Engineer} from Rm{William Robotham - Chief Engineer}/Std. c. Da.{Bernard Day - Chassis Design} Rm{William Robotham - Chief Engineer}/Std.1/MH.{M. Huckerby}14.1.38. WRAITH WIDNEY BONNET HINGE. While scheming the above hinge for Wraith, will you please endeavour to incorporate the idea of using the bonnet hinge rod as a single central radiator stay, already suggested for B.30. We think that a single central stay is better than two stays from the point of view of radiator shake, and in any case the central stay will have very little to do. We have tried a car with no stays whatever and the radiator movement was negligible. It looks as though this suggested arrangement would fit in reasonably well on the Wraith bonnet.
