| To BY.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} c. to DA.{Bernard Day - Chassis Design} +7460 Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}3/LG15.5.29. TWO-LEVEL DEVICE FOR 20 HP. CAR. 45460 With reference to BY/CGH{W Clough}11/G9.5.29. We think that this can be deleted now that we have a K.S. petrol gauge. The main difference between the 20 HP. and the S.S. however is the fact that the S.S. has the reserve in the autovac. As this is only fitted to help the vacuum pump, however, we do not think that it is necessary on the 20 HP. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
