Bailey - Chief Engineer} c. to HPS. {Horace Percy Smith - Experimental Factory Mgr} 1297 Rm {William Robotham - Chief Engineer} /Wym. {G. Harold Whyman - Experimental Manager} 16/JH.14.5.37. Air Silencer Support. Phantom III Four Port Head. In reply to your memo. E {Mr Elliott - Chief Engineer} /PSN.1/M.5.5.37. it was certainly agreed to test a Phantom III air silencer on the four port head without the stays to the induction pipes and this has been done by running it on 35-EX for 20,000 miles. We cannot understand from where you received the information that this had proved satisfactory, in consequence of which you have instructed the deletion of the stays, as the body of the air silencer on 35-EX has worked loose on all its rivets, and this we attribute to the lack of the support of the stays.
