| 1110 Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}2/AP. 6th December 1937. Messrs. Ferodo Ltd., CHAPEL-EN-LE-FRITH For the attention of Mr.Longley Dear Sirs, We may require a number of discs of a heat insulating material 1.000" dia. X .060" thick to fit between the end of clutch thrust springs and the pressure plate. This applies to certain earlier 20/25 Rolls-Royce cars and the 3½ litre Bentley, in which the thrust springs are partly recessed into holes in the pressure plate, and we have found cases in which springs have become overheated as a result of excessive clutch slipping. Would you please quote us per gross for suitable discs, and also kindly let us have a small sample of the material you would recommend. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
