| X8664. Ey/RD. from EFC. EFCl/AD3.7.30. X.8664. 40/50 HP. HIGH OUTPUT DYNAMOS (56 COIL) Referring to your Ey/RD6/W2.7.30 we will look into this matter, but understand, as mentioned in conversation, that you will arrange for us to receive two of the machines in question for trial so that we may ascertain the reason of the output being less for the given control brush position than that referred to in the specification.
