Clapham} Ev.{Ivan Evernden - coachwork}11/JH.17.5.40. re Rear Springs Rippletto. After consultation with Rm{William Robotham - Chief Engineer}/Clm.{D. D. Clapham} and Ev{Ivan Evernden - coachwork}/DB.{Donald Bastow - Suspensions} we have decided that the best approximation we could make for the poundage of the rear springs for Rippletto is 850 lbs. In every other respect the springs should be the same as B.V. This will make the car stand in all conditions at the height projected. Ev.{Ivan Evernden - coachwork} | ||
