| X8664 By/Mtn. from EFC. EFC1/T14.6.28. PHANTOM DYNAMO MODIFIED FOR HIGHER OUTPUT. We hand you herewith dynamo CH.85.M which is the one originally belonging to this Dept. which has been modified by Mr. Brock and subsequently tested by us. The output curve of this machine is now higher than the standard though it is not quite so satisfactorily high as the previous machine, similarly modified, which we passed to you. EFC. | ||
