| To By.{R.W. Bailey - Chief Engineer} from Rm{William Robotham - Chief Engineer}/Std. c. to E.{Mr Elliott - Chief Engineer} 6003 BENTLEY WATER TEMPERATURE THERMOMETERS. We note that although on the 25/30 and Ph.III. chassis on Production the water thermometer capillary tubing is coiled in a manner to provide the maximum flexibility in the direction of the engine movement, this is not done on the Bentley thermometer, the coils being in a horizontal instead of vertical plane. In view of the fact that the engine movement on the Bentley is considerable and that we have had several breakages of capillaries in experimental cars, we think that the coiling of the capillary should be brought into line with 25/30 and Ph.III. immediately. A scheme is in existence for this alteration - RR.Sch.834 and the same method of coiling should be adopted with the flexible armoured capillary which is being standardised shortly.
