| W/S Sg.{Arthur F. Sidgreaves - MD} from Hs.{Lord Ernest Hives - Chair} X4078 Hsl/LG22.8.22 HORN FOR GOSHAWK. X1163 X4078 The Cobra horn fitted to the Goshawk limousine is the best horn, and on that car it looks quite neat. The one disadvantage is that it collects water and when it has water in it, it interferes with the note. We would prefer not to have the bulb horn fitted under the bonnet. Owing to the fact that the Klaxon horn button is fixed on to the centre of the steering column and is very convenient in that position when driving, we doubt whether the bulb horn will ever be used to any extent on the Goshawk. The only reason for carrying one would be in certain districts on the Continent where the Klaxon horns are not permitted. Hs.{Lord Ernest Hives - Chair} | ||
