| COPY. To Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} From GWH.{George W. Hancock - Head Chateauroux} Cricklewood, Oct.24th., 1936. BONNET COMPLAINTS. Upon investigating these complaints I find that the reports issued by Hd.{Mr Hayward/Mr Huddy} are entirely misleading. Actually, during the last six months at Cricklewood there were not more than a dozen cars which had anything done to the bonnet panels. The chief trouble is the settling down of the Ferodo strips which allow the bonnet to rattle. The remedy is to wedge up the strips. It would appear that the Ferodo strips are not thick enough. Of course a better design would be to use rubber, but not like the Phantom lll which is wrong. It should be like this - [Drawing of a bonnet section with labels: Bonnet, rubber, dash.] Instructions should also be given to the coachbuilders to support the overhang of the bonnet with a rubber strip as we get the following result. A mark shows at this point where it is supported by the dash. [Drawing of a bonnet side profile showing support point.] G.W. Hancock. | ||
