Rolls Royce Limited, DERBY. Dear Sirs, For the attention of Mr. H.{Arthur M. Hanbury - Head Complaints} E.{Mr Elliott - Chief Engineer} West. re: CAR RADIO. Thank you very much for your letters of the 30th ult. and 3rd instant. I am sorry that owing to my temporary absence these have not been dealt with before. We are interested to hear that you have been carrying out some tests with the Motor Rola Car Radio, and have noted your remarks regarding the Mallory Vibrator. We have in fact tried this particular make of vibrator, and have some on test now, and we have already come to the conclusion that they are one of the most successful. With regard to bulk, however, we would point out that although the vibrator itself is quite small, a considerable amount of smoothing equipment is directly associated with it, and this is not immediately evident on looking into a receiver containing these filter parts. Our separate rotary unit has been reduced in size to a point where it is very little larger than a separate vibrator unit with filter. With regard to the proposed radio equipment on a 40/50 h.p. Enclosed Limousine for your Stand at Olympia, we would suggest either a Direct Control Receiver mounted IMPORTANT NOTICE.
