| x331) To Hl. Hs{Lord Ernest Hives - Chair}/Std.11/KW.7.1.35. We send you herewith a Buick hot-spot heat control valve, including flap valve, valve spindle and valve spindle bush. This valve operates in a stream of hot exhaust gas and we should like to know the composition of the materials used. Will you therefore ascertain for us the materials from which each of the above parts is constructed. We do not mind if you scrap these parts in doing so, as they were obtained for this purpose.
