| W/SW 113/Wst WST X6016 To L. from Sg.{Arthur F. Sidgreaves - MD} re Battery Charging 20/25 HP. Sg{Arthur F. Sidgreaves - MD}7/E4.7.32 Copy to Mr. BY.{R.W. Bailey - Chief Engineer} Re/Int. Car. PH. I attach copy of a memo. from PH which apparently was not sent to you. Regarding the question of the modified switchbox when available being utilized in connection with our existing 20/25 dynamo, this seems a good suggestion if, as I assume, it would give us some benefit earlier than by waiting for the introduction of the P.II dynamo on the 20/25 chassis, which must necessarily be a long way off. I should like to have your opinion on this point. Regarding the question of doing away with the ammeter and having a volt-meter instead, this is a matter which I think might be discussed at our next conference. Sg.{Arthur F. Sidgreaves - MD} Enc.
