SPECIAL LUCAS HIGH FREQUENCY HORN NO. HF.{H. W. Frost - Coachwork Inspector}722 We have received from Messrs. Lucas a new type of high frequency horn embodying the best features of the Bosch and Lucas in one. We are anxious to test these types of horns as a scheme is coming through for fitting them as standard on chassis. We wish to obtain one of these for 19-EX but before sending away for it we would like to test the existing one on chassis 19-GIV. Will you therefore please arrange for this horn to be fitted to the front radiator cross member on this car. We have drawings for a special bracket for mounting this horn in position as you will remember a similar type was fitted to 18-GIV. Hs{Lord Ernest Hives - Chair}/Wst. | ||
