| X1069 To C. from R.{Sir Henry Royce} c. to CJ. c. to BJ. c. to HS.{Lord Ernest Hives - Chair} RL/M20.4.25. X.1069 X.1163 I worried you to look into the electrical vibrator instead of a klaxon. All the newer big cars seem to have these in France. I am now getting tired of the noise and think it is no better than the klaxon, so do not let my suggestions influence you seriously, because there seems little to choose. All noises are irritating: the least object-ionable SEEMS to be the low note bulb horn - (Boa Constrictor). R.{Sir Henry Royce} | ||
