| X6005 By/RD. from Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.1/ADL 2.3.32. We attach herewith as requested a curve showing the ampere-speed characteristic of a 48 coil 20/25 dynamo "set safe" for chassis where a demand is made for a higher output dynamo with no half charge resistance fitted i.e. cars prior to T. series.
