| W/S. Cx.{Major Len W. Cox - Advertising Manager} From Hs{Lord Ernest Hives - Chair}/Wst. +6183. Hs{Lord Ernest Hives - Chair}/Wst.7/MA.26.10.34. Re. Radio Sets. Referring to your Cx.{Major Len W. Cox - Advertising Manager}1/KW.25.10.34., we do not agree to the feed for the radio set being taken direct from the battery. We consider it should be taken from the accessory fuses supplied on the standard distribution board on the engine side of the dash board. We have ourselves fitted up a chassis with radio set complete in which the feed is taken from the distribution board and no increased in ignition interference has been noted at all. We return Hooper's letter herewith. Hs{Lord Ernest Hives - Chair}/Wst. | ||
