| X6004. Sft{Mr Swift}/Mr.Brock. from EFC. EFC1/AD21.1.31. X.6004. PRODUCTION MEDIUM OUTPUT DYNAMO Y.55.M. We have completed our observations on the above machine and are satisfied that the output performance is quite O.K. A specification of test for this type of machine will be sent you as soon as the necessary confirmation of these observations has been obtained on other machines. EFC/CAP. | ||
