X.5661/3. 20/25 DYNAMO OUTPUT ON U.S.A. CARS. Referring to Hs{Lord Ernest Hives - Chair}5/MJ16.1.31 and your Sg{Arthur F. Sidgreaves - MD}4/M19.1.31 we are taking the necessary steps in this matter. We are asking Ey. to give the necessary drawing for the modification to the pole pieces and at the same time we are preparing curves (on our new 14.0 volt basis) which will shew the modification which may be expected in the output.
