Eric Platford - Chief Quality Engineer} Da.{Bernard Day - Chassis Design} c. to E.{Mr Elliott - Chief Engineer} R4/M1.2.22. RE HORNS X.1069. With reference to horns for our cars, some years ago we used to fit a logn horn with a deep note. I believe they were called Boa Constrictors. I think if we have not already done so, it would be advisable to get this type made standard for the Goshawk, and also used on other cars in larger or smaller sizes. R.{Sir Henry Royce} | ||
