B/Ev.{Ivan Evernden - coachwork}1/M.7.7.37. Re: WRAITH III. FRONT WHEEL HUBS. It is suggested by HPS{Horace Percy Smith - Experimental Factory Mgr}/Hollingsworth that the inner bearing retaining cover of the front wheel hub GW.1650 be attached by six studs in the place of ten as shown on our scheme in the interest of economy. We agree to the proposal being tried experimentally, but we are a little afraid of oil leaks. It may be necessary to increase the stud size from 2BA. to a ?. The locking plates will now become rather long. E/EV.{Ivan Evernden - coachwork} | ||
