| 623 To RHC {R. H. Coverley - Production Engineer} /EM. Rm {William Robotham - Chief Engineer} /Wym. {G. Harold Whyman - Experimental Manager} 7/JH.16.9.38. Wraith Exhaust System. Further to our memo. Rm {William Robotham - Chief Engineer} /Wym. {G. Harold Whyman - Experimental Manager} 8/JH.9.9.38. it has now been decided by Rm. {William Robotham - Chief Engineer} to allow the first 100 silencers to be built up to the present specification, because all the pipes EW.1804 are already drilled, and this is the pipe we had proposed to modify. We would however like you to hold up the drilling of any more of these pipes until you hear further from us. Rm {William Robotham - Chief Engineer} /Wym. {G. Harold Whyman - Experimental Manager} | ||
