X.8500 X.7260 X.8500 X.7430 We have explained that the proposed bonnet improvements depend on the use of a stiffened dash. R.{Sir Henry Royce} is very anxious to use a cast dash similar to that which went through the 10,000 miles trial on EAC.8. The only definite objection we have heard raised to this dash is that the engine vibrations are more pronounced than with the standard arrangement. We should like this objection to be confirmed if possible, especially as there is another cast dash in existance, namely, that on EAC.7. Should this objection prove not to be founded on fact, there appears to be no reason why the cast dash should not be put forward for standardisation at the first opportunity. As arranged on EAC.7. & 8 the cast dash was bound up with modified steering and seating positions, modified pedals etc. There was also included on these two chassis a rather shorter bonnet, and radiators with integral shutters. We should like Sales to say whether, owing to the difficulties of introducing these modified seating and steering positions, etc. it would facilitate the introduction of the cast dash if we were to arrange it for the existing steering positions, pedals, etc. This can be easily done but means slight modif- ication to the actual casting. We presume that it would also facilitate intro- duction if it were not wrapped up with the shorter bonnet and the integral shutters, as we believe there is a certain amount of opposition to both these latter. We should be glad if something could be said about this. We think it will be understood that the shortened bonnet is quite a seperate thing, obtained by pushing the engine forward, and is not directly connected in any way with the new seating positions.
