This arises out of it having been agreed that, whilst we like these horns and want to standardise them, we do feel perhaps we ought to know a little more about their ability to stand up to ordinary road usage, particularly under rather strenuous conditions. If these horns reach you shortly could you have them put on one of the cars doing the 10,000 miles in France to see whether they fall to bits or not ? Enc. Copy of Cx{Major Len W.
