| -2- Rm{William Robotham - Chief Engineer}11/R.10.2.37. Cont'd.{John DeLooze - Company Secretary} (2) Exhaust System. to GWH.{George W. Hancock - Head Chateauroux} This main silencer is so simple and robust that we do not anticipate any trouble with it at all. (3) Wraith Suspension & Steering Levers. Fitted to 35-EX, and have effected a marked improvement in the steering. (4) Increased Clutch Pedal Travel. This is fitted to 35-EX and would be much appreciated by customer. (5) Increased Hand Brake Leverage. The present hand brake needs adjusting too quickly. There is one other item which would be of considerable value to Sales Dept., where the majority of P.III cars are located, i.e., the new Silent Tread Tyre. It is too early to say "go" on these tyres, but stocks of the existing type of tread could with advantage be kept low, particularly in view of the fact that we understand Rolls-Royce are the only people to take this particular type of tread, and we may have difficulty in getting Dunlops to absorb any which have been made.
