[Handwritten Notes] Hs{Lord Ernest Hives - Chair} [STAMP] DEC 3 1926 X7260 [crossed out] X8500 X7500 [underlined] CAST DASH AND BONNET DESIGN. With reference to BJ28/E291126.. there are one or two items on the list to which we think we can give replies - (1) The cast dash is a development of the stepped dash, which it replaces. (2) & (3) As originally designed for EAC. 8. the bonnet was somewhat shortened, and this is the dash which has done 10,000 miles. There was also included in this chassis improved seating positions. R.{Sir Henry Royce} realises that the introduction of these improved seating positions may involve some delay, and since he is very anxious to get the cast dash into production as soon as possible, has agreed to one being designed which will not alter the length of either scuttle or bonnet, and which will not be tied up with the modified seating positions, with their altered steering columns and pedals. We are at present engaged in the design of this dashboard, which follows exactly the lines of EAC. 8. except in the position on the chassis. The advantages of the cast dash generally are that it is very much stiffer than the present dash, and we are able to support the steering column rigidly from it without additional stays, and without depending on the instrument board, in addition to which it firmly supports the radiator. There are also other advantages as regards additional room on the engine side, superior scuttle isolation, increased neatness in the fittings on and around the dash.
