| To By.{R.W. Bailey - Chief Engineer} c to Rm.{William Robotham - Chief Engineer} Kingsbury. Nov.13th.1936. Bentleys. Complaints Push rods bending. This complaint is on the increase with the 4 1/4 litre. I have not reported this trouble previously, but there are too many coming along which points to weakness. They are bent as much as 1 m/m (milli metre). GWH.{George W. Hancock - Head Chateauroux} | ||
