| X6016 E.2/HP.8.7.32. To BE. from E.{Mr Elliott - Chief Engineer} c. Wor.{Arthur Wormald - General Works Manager} By.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Hs{Lord Ernest Hives - Chair}/Let. Ox. PN.{Mr Northey} re Battery Charging 20/25 HP. In reply to your memo Sg.{Arthur F. Sidgreaves - MD}7/E.4.7.32, the 20/25 HP. switchbox re-arranged by BY/RD to give 2 stage and full charge will enable us to utilize the recently improved output of the 20/25 dynamo. We are putting this up to R.{Sir Henry Royce} as soon as the dynamo output curves on all stages of charge are available. E.{Mr Elliott - Chief Engineer} | ||
