| X6074 ROY{Sir Henry Royce}/GEA. From Hs{Lord Ernest Hives - Chair}/AJL. Hs{Lord Ernest Hives - Chair}/AJL.2/MJ.23.7.30. KLAXON WIND HORN. We have tested the klaxon wind horn No.109. It certainly has a loud and penetrating note, but is much more suitable for a char-a-banc than a Rolls-Royce car. It is altogether too blatant and noisy for our use. Under the circumstances we do not see any object in testing it out further i.e. as regards wearing qualities, life etc. Hs{Lord Ernest Hives - Chair}/AJL. | ||
