| X.3653. Extract from EH2/LG10.6.L9. BYE-PASS FOR 40/50 CHASSIS. Our experience with 49-GB which is fitted with a blind and a thermometer, has shewn that it is not essential to have the Control operated from the driver's seat. We consider the amount of blanking on the radiator under ordinary circumstances should not need altering more than four times during a year i.e. at every season. The temperature during the whole of the time would be maintained from 70 to 95°C. EH. R.R.L. 285 & 286 (1200 S) (T. 671. 22-5-19) CL. 2376 | ||
