| Sg.{Arthur F. Sidgreaves - MD} From Hs{Lord Ernest Hives - Chair}/Wst. X6074 Hs{Lord Ernest Hives - Chair}/Wst.17/MA. 23.3.32. ELECTRIC HORNS. X6032 X6074 With reference to your Sg.{Arthur F. Sidgreaves - MD}8/E.22.3.32., we do not think you have seen the Latest Lucas HF{H. W. Frost - Coachwork Inspector} Alto horn which has just been produced as a result of their collaboration with the Bosch Co., and we are accordingly sending you a sample horn type HF{H. W. Frost - Coachwork Inspector}722 for trial. This horn is arranged to be mounted either on the head lamp pillar or the front cross member in as rigid position as possible. Any vibration in the mounting spoils the tone. With regard to the Klaxon horn referred to in your note we are obtaining a sample horn for test as requested. Hs{Lord Ernest Hives - Chair}/Wst. | ||
