| Sg.{Arthur F. Sidgreaves - MD} From Hs{Lord Ernest Hives - Chair}/Wst. 86185 Hs{Lord Ernest Hives - Chair}/Wst.7/MA.12.12.34. DASHBOARD ILLUMINATION. Answering your Sg.{Arthur F. Sidgreaves - MD}17/E.3.12.34., the reason why the Buick speedometer is illuminated so extremely well is apparently because the dial is convex. We have informed Messrs.Smith's of this fact and they have been asked to supply us with a clock and speedometer fitted with convex dials to try out on the new instrument patch on the Spectra.
