| To Py. from R. {Sir Henry Royce} c. to Wor. {Arthur Wormald - General Works Manager} c. to BY. {R.W. Bailey - Chief Engineer} c. to Ha. c. to PN. {Mr Northey} c. to EP. {G. Eric Platford - Chief Quality Engineer} c. to Br. {T. E. Bellringer - Repair Manager} c. to H. {Arthur M. Hanbury - Head Complaints} X2628 PS/M10. 8.22. RE. THICK LEAF REAR SPRINGS. X. 2628. X. 4261. X. 4426. Never fit these to new cars. Always replace with thin leaf springs on existing cars when changing. Always change to thin leaf if customer complains. Add Hartford shock dampers to thin leaf springs also. Since we charge a good price for the chassis, do all we know that it shall be the best 1st. thinn leaf springs, 2nd. gaiters, and 3rd. shock dampers. The axle will then better hold the road - brakes and shunting will be more satisfactory - the car will be steadier at high speed and there will be no squeaky springs. The present cord tyres require all the damping we can give to the back axle, and even then they must not be p-umped hard. R. {Sir Henry Royce} | ||
