We are quite satisfied with the effect of the Dual High Frequency Horns fitted up as we have had them fitted on the Continental Phantom II, i.e. on the headlamp brackets immediately under the headlamps, and we should like you to standardise this arrangement as soon as you can on all 40/50 h.p. models. It now, I think, only remains for you to tell us when you can introduce them. We on our part are trying to get Lucas' to give us stainless steel parts for these horns instead of chromium plating as at present, so as to be more in keeping with our radiator and lamps.
