Listed Gaw To Rm.{William Robotham - Chief Engineer} from Ev.{Ivan Evernden - coachwork} c.c. to Rm{William Robotham - Chief Engineer}/HH. 1022 Ev.{Ivan Evernden - coachwork}11/JH.26.6.40. Carburetter Air Silencer Rippletto. On PL.253 we shew the carburetter air silencer and support for Rippletto when the engine is fitted with a single downdraught Stromberg carburetter the same externally as that fitted to Wraith III. We communicated with the AC-Sphinx Sparking Plug Co.Ltd. giving them the necessary engine particulars to enable them to recommend an air silencer. They suggested their model No.1573619 which they have recently supplied for an engine almost identical in size. Actually it appears to be the Wraith III Air Silencer, shortened in length. Suitable bosses for the support are shewn on the aluminium rocker cover.
