| X6016 To E.{Mr Elliott - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.3/AD30.6.32. X6005 20/25 HP. DYNAMO CHARGE We are sending you as requested, three blue prints showing the rates of dynamo charge suggested for the 20/25 in the event of the 40/50 dynamo being fitted. This gives a winter and summer charge position incorporating two grades of resistance and the full dynamo charge when head lamps are on only. We shall be glad if an early decision can be made with R.{Sir Henry Royce} about the whole question of dynamo charge on all our chassis. Hs{Lord Ernest Hives - Chair}/Wst. | ||
