| X6094. Roy. {Sir Henry Royce} from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 2/ADL 7.2.31. X.6094. RECTIFYING VALVE FOR H.T. We have duly perused the letter ref. WN/WL. of the 13th inst. from the Edison Swan Electric Co. concerning a valve of the above type. We have noted that they would be pleased to make a valve for us if we would favour them with certain particulars. With regard to the specification of these particulars, as this is somewhat lengthy we have typed this out on separate sheets (two copies) so that you can forward one copy to the Edison Swan Electric Co. directly. We trust that the information contained in this specification will be sufficient to enable them to produce a valve of the type we require Two copies of specification attached. EFC. {E.
