| To By/NS.{Norman Scott} 622 Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager}4/JH.7.9.37. Wraith III Engine Mounting. Will you please prepare 2 schemes for taking engine torque in conjunction with the raised front engine mounting on Wraith chassis. We should like one scheme with the torque rubbers working in shear, and the other with them working in compression. Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} will supply the rubbers. Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} | ||
