Munro}/S(B) BONNET REST ANGLE - WRAITH 111. Herewith the following scheme :- F.CD.66 Modifications to Bonnet Rest Plate. This new scheme is necessary for the following reasons :- (1). Engine mounting is modified. (2). Controls have been altered. (3). Stiffener has been added to the Side Spare Wheel Carrier. (4). The Rest angle fouled the frame. These various changes have made it possible to clean up the rest angle, and it now becomes a simple folding free from indentations. DA.{Bernard Day - Chassis Design} | ||
