| To By.{R.W. Bailey - Chief Engineer} from BN.{W.O. Bentley / Mr Barrington} copy c. to Hs.{Lord Ernest Hives - Chair} Bn{W.O. Bentley / Mr Barrington}3/W22.8.19. RE RADIATOR FOR 40/50 CHASSIS. X.3456 With reference to EY/JH4/H13819, efficiency tests of the 7 mm. and 8 mm. tubes have not yet been carried out. Our impression is at the moment that it is unlikely that we shall be able to afford to reduce the amount of surface that is entailed by the use of 8 mm. tubes. At the moment we should continue with the use of 7 mm. tubes and the further 250 radiators on these lines can therefore be ordered. Bn.{W.O.
