| (3) Hield This would do away with signalling windows, and the attendant wide doors and draughts when open. We are investigating this with a view to getting such fittings available. (9) INSTRUMENT BOARD. Our internally illuminated framed instrument group as revised should be adequate. There should be a second lamp, preferably under the scuttle rail, a coachbuilder's fitting, which can be put on for finding things dropped in the scuttle, map reading, etc. (10) WIND HORN. The law, an old relic of the past, says one must have a wind horn. In this country thousands of cars are now sent out with only an electric one. In France a wind horn is still essential by law, and the law is enforced. The cobra horn is large and expensive. We recommend that when it is fitted it should be placed on the steering column under the bonnet as on experimental cars, and be the type without a flared trumpet. All these are more or less our fittings. The coachbuilders fittings we can only influence, but not control. * DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} | ||
