| To Da.{Bernard Day - Chassis Design} from E.{Mr Elliott - Chief Engineer} c. Sr. Wdr. Hs.{Lord Ernest Hives - Chair} Br.{T. E. Bellringer - Repair Manager} re Experimental Bensport Chassis with existing Japan I engine unit, and 20/25 gearbox. We send you herewith blueprint of LeC.3280 showing the chassis arrangement made for the above. The pedals as shown are the nearest likeness that can be obtained to the final design, and their position has been maintained relative to the steering column at the expense of some increase in pedal pressure for the sake of safety in driving. The hand brake and gear change levers have been shortened to suit the body and to be as like the final design as possible. We have been compelled to cut away some portion of the wells for the rear footboards on account of the brake ropes, but we do not think this will matter much as the position can still be judged by reference to the major portion of the well not affected. The front body bracket on the driver's side has had to be moved back to clear the hand brake mechanism but as the bracket at the present moment is not directly opposite the front pillar on the body this does not appear to matter very much. The proportions of the brake linkage have been fixed up in conjunction with the Experimental department, and the quantities are given on the print. The engine mounting as you are aware follows very largely the present 20/25 practice, but we are proposing for the final design to convert this to the J.3. pattern as the latter, we think, is more simple and economical and can be used provided that the torque reaction dampers are not required for damping high speed chassis frame oscillations.
