Hancock - Head Chateauroux} 1137 Rm{William Robotham - Chief Engineer}10/R.25.1.37. AIR CLEANER. It occurs to us that the Voke's filter which we fitted to the earlier type Bentleys may, in some cases, be getting choked up. We should like to get hold of one of these filters from a car which has done a big mileage under all sorts of conditions, and see whether there is any indication that this is happening. We should also be experimenting with the oil carb. cleaner which does not get clogged up. This would be an ideal filter for a job like the P.III in Africa. Rm.{William Robotham - Chief Engineer} | ||
