| To RHC. {R. H. Coverley - Production Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} X4430 EFC {E. Fowler Clarke - Electrical Engineer} 1/T20.3.24. X.4430. GOSHAWK CONDENSERS. We are handing you herewith three packets of paraffin wax of different melting temperatures, as labelled. Would you kindly have made up three otherwise standard condensers, but utilising the white untreated paper received from U.S.A. and handed to you with our EFC {E. Fowler Clarke - Electrical Engineer} 6/T30.1.24, one sample of each of the three paraffin waxes to be used in the construction of each condenser. Would you kindly let us have back the unused paraffin wax as this is sometimes useful in our Dept. We have still by us for test two condensers which you made up previously with the paper referred to above, but it was considered that the paraffin wax used for these two was probably not of the purest quality.
