Rm. {William Robotham - Chief Engineer} HPS. {Horace Percy Smith - Experimental Factory Mgr} E.6/HP.24.5.37. Wraith Chassis - Front Suspension Housing. With reference to Messrs. Deritend's letter in which they state that new dies at a cost of £150 would be required to carry out the lightening modification on the above piece, I do not think we should proceed with this at the present time. At the same time, I do not think this piece is suitable for either die cast aluminium or malleable as a fracture in the dumb iron lug portion would have serious consequences. My view is that we should carry on with the dies as they are until we know more about the Wraith chassis generally. E. {Mr Elliott - Chief Engineer} Correspondence returned herewith. | ||
