Roy.{Sir Henry Royce}FD.{Frank Dodd - Bodies} W/Supt. STEADMAN Noted Ruf/SMD{J. Smedley} Wraith II Bonnet. On Phantom III and 25 H.P. cars we have standardised one slope for the back end of the bonnet and we wish to do the same on Wraith II. We wish to standardise the pivot having an 8 3/4" overhang and 12° back slope. This was one of the two bonnets sent to you on Loc.5203. The standard bonnet will be equipped with shutters as shown on that scheme and will be used on all chassis, the 11 1/4" overhang bonnet being abolished. We regret that the body for the second Wraith II body, the continental touring limousine for chassis 25.U.6. has been built for the 11 1/4" overhang bonnet and therefore this chassis will have to have such a bonnet but all future experimental cars will have the new proposed standard bonnet. Will the Expl. Dept. kindly note that the 11 1/4" overhang bonnet has to be provided for 25.U.6. Ev.{Ivan Evernden - coachwork} | ||
