| To By/Ald.{F. Allwood - Experimental Design} from Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} c. By.{R.W. Bailey - Chief Engineer} c. Da.{Bernard Day - Chassis Design} Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}6/MH.{M. Huckerby}9.8.38. WRAITH FRONT SHOCK DAMPERS. The B.III steering is very free from joggles and this is attributed to the type of valve used in the dampers. Wraith can only be kept free from joggles by the introduction of sponge in the side steering tube and this means that all Wraiths are on the verge of low speed wobbling. Will you see if the B.III valve can be adopted to Wraith front dampers, and if so instruct two sets of the necessary parts. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
