| To By/Ald.{F. Allwood - Experimental Design} from Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie} c. By.{R.W. Bailey - Chief Engineer} 646 Rm{William Robotham - Chief Engineer}/Les.2/MH.{M. Huckerby}27.1.38. Will you please let us have drawings for the attached 8.5" initial deflection springs. We are requiring one pair of 8.5" springs so that we can reproduce the Packard spring deflection on a Wraith. We think the drawings should state the maximum thickness of packing washers permissible with each spring. Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie} | ||
