Ha/Rm.{William Robotham - Chief Engineer} WMG. noted Hs{Lord Ernest Hives - Chair}/sco WRAITH II. STEADMAN Bonnet. We have already sent to you particulars of the two types of bonnet on Wraith II with the exception of the details of the side plates. We send you herewith LeC 5203 showing the remaining information for both types of bonnet. Phantom III bonnet catches and bonnet lock are used, and also Phantom III shutter mechanism for the two shutters which we propose to fit as standard in each type of bonnet. It is not proposed to have a louvred bonnet of any sort. The original angles for the backs of the bonnets were respectively 12° and 18°. We have found it necessary to modify these to 12° and 17° keeping the overhang at the top hinge the same. Ev.{Ivan Evernden - coachwork} Att: LeC.5203. | ||
