| Martindale. There does not seem to be any reason why the works should not do as Glo. H.{Arthur M. Hanbury - Head Complaints} recommends. Rm.{William Robotham - Chief Engineer} from Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} Hawkins Car is in again with squeaks. Rm{William Robotham - Chief Engineer}/GWH{George W. Hancock - Head Chateauroux}2/R.20.5.37. Have we any leced lining for him. Rm{William Robotham - Chief Engineer} (BENTLEY & 25/30 BRAKES) To make the pilot shoe as effective as it should be to prevent squeaks, the load to depress the tip of the shoe should be not less than 70 lbs. Cars are coming out of the Works with a load of 40 and under, the brakes squeaking before the car reaches the customer. Rm{William Robotham - Chief Engineer}/GWH.{George W.
