| X6016 Hs{Lord Ernest Hives - Chair}/AJL. from EFC. EFC4/AD1 4.1.31. X.6016. TWO RATE CHARGE SCHEME. X.6004. Answering your Hs{Lord Ernest Hives - Chair}/Lidl/MJ14.1.31 we were already arranging to modify the two rate charge schemes on these cars to which it has already been applied, having already put through a requisition for the necessary resistances. In regard to medium output machines, we have two of these available which we are taking steps to prepare in a similar manner to that in which we prepared the machine for 58-GN. We will in due course instruct RHC.{R. H. Coverley - Production Engineer} to make the change. 19-EX is already fitted with medium output 48 coil machine 20-EX " " " " 48 coil high output machine without the two rate charge schem therefore the chassis involved are 24-EX, 25-EX, 27-EX in addition to 22-EX. In which order do you consider these cars should be altered to be like 58-GN? EFC. | ||
