It is also necessary to make the outlet orifice for the defroster in the form of a narrow slot (say .100 - .125" wide) to give sufficient air velocity to carry up the windscreen. We are rigging up what we consider a suitable de-froster, within the limits imposed by other considerations on 1.B.50 car in the Exp. Garage and when complete we would like Ev.{Ivan Evernden - coachwork} to make a scheme drawing applicable to B.V. B.50, and Wraith, so that coachbuilders can be shown exactly what is required. Defrosters identical with this scheme should be fitted to Sg{Arthur F. Sidgreaves - MD}'s Wraith car. Rm{William Robotham - Chief Engineer}/Std. | ||
