Mr Wormald has asked me to send you the following report from Mr Kirby of the Repair shop, written from the Bombay depot concerning the use of fibre in India. "Fibre should not be used in this country if possible as it contracts and expands to a great extent. When used as bushes in spring shackles and springs it causes same to squeak after a car has run a few miles, however much they are oiled. N.B. Cars which we have fitted with phoshor bronze bushes have not given any trouble. Fibre when used in connection with the make and break of the magneto often causes the make and break to stick up. N.B. Standard cars in Delhi had this trouble" As previously advised we are waiting Mr Johnson's instructions concerning the correction of spring suspension bushes according to your This sheet must be filed with the correspondence to which it refers. | ||
