| To SFX/Mr. Brock. X5723 ds EFC4/T2.3.27. RE DYNAMO CX.{Major Len W. Cox - Advertising Manager}65 FROM PRODUCTION. We have duly looked over and tested this machine and the only thing wrong of any consequence is that the clearance between the negative brush holder and commutator is .055" which is above the absolute limit of .041". This may lead to brush noise. We return the machine herewith. EFC. | ||
