| WST X6032 see me Hs{Lord Ernest Hives - Chair} 9 6 S/W. Hs{Lord Ernest Hives - Chair}/Wst. High Frequency Electric Horns Mounted Under the Apron. Cx{Major Len W. Cox - Advertising Manager}5/KW29.10.32. With reference to Hs{Lord Ernest Hives - Chair}/Wst3/AD241032 to BY, a copy of which we have received, I note you say that with this arrangement of dual high frequency horns " mounted under the head lamp Pillars" the sound is very pronounced,etc. Would you please let me know exactly where you mean by under the head lamp pillars. The horns that we have been experimenting with have been mounted one each on the headlamp bracket immediately below the headlamp, where they seem very effective. Do you agree that this is the right position, please ? Cx.{Major Len W. Cox - Advertising Manager} | ||
