| WST r6032 S/W. Hs{Lord Ernest Hives - Chair}/Wst. Electric Horns. Cx{Major Len W. Cox - Advertising Manager}18/KW5.9.34. We have considered the suggestion made in your Hs{Lord Ernest Hives - Chair}/Wst.5/MA30.8.34, but would prefer not to have the R-R monogram introduced on electric horns. We in London are of the opinion that this question can be left as it is except of course for any more distinctive grille which Lucas care to introduce in the horns themselves on their own initiative.
