| 606. AEPA Smith SECRET. WRC. O. {Mr Oldham} to:- Mr. Par.Tins. E {Mr Elliott - Chief Engineer} /HDY. {William Hardy} 4/HP.17.3.37. Wraith III Rear Brakes. We send herewith N.Sch.5076 showing a modification to the rear brake bell crank levers on the frame, to delete the brazing. A split clamped and keyed lever is shown on the recommendation of Mr/Hr Morris, as the cheapest way to do this job. The use of a one piece forging is not thought to be practicable. This drawing shows a stop pin with the taper deleted as requested by HPS. {Horace Percy Smith - Experimental Factory Mgr} E {Mr Elliott - Chief Engineer} /HDY. {William Hardy} N.Sch.5076 herewith. | ||
