| WST X6032 See me HS{Lord Ernest Hives - Chair} S/W. Cost Dept. c. to Hs.{Lord Ernest Hives - Chair} re- 19-G4. Cx{Major Len W. Cox - Advertising Manager}12/KW30.8.32. On this car, which Sg{Arthur F. Sidgreaves - MD} used in France recently, you had two Lucas High Frequency horns coupled up together and working in synchronism. Can you please let us know how the retail price of this arrangement compares with :- (1) that of the Klaxon horn recently abandoned, (2) that of the Lucas single High Frequency horn recently standardised on the 40/50. We are thinking of standardising the dual horn equipment on the 40/50 provided the cost does not turn out to be excessive. Cx.{Major Len W. Cox - Advertising Manager} | ||
