| 623 To By {R.W. Bailey - Chief Engineer} /NS. {Norman Scott} c. to LA. {L. A. Archer} Rm {William Robotham - Chief Engineer} /Wym. {G. Harold Whyman - Experimental Manager} 6/JH.23.6.38. WRAITH EXHAUST SYSTEM. This is to confirm that By. {R.W. Bailey - Chief Engineer} and Rm. {William Robotham - Chief Engineer} have agreed that all production Wraith exhaust systems should have the downtake pipe, front expansion box and front intermediate pipe made in staybright steel. This cancels the previous instructions for mild steel nickel plated. Will you therefore issue the necessary instructions to all concerned. Rm {William Robotham - Chief Engineer} /Wym. {G. Harold Whyman - Experimental Manager} | ||
