| ROLLS-ROYCE LTD. INSTRUCTIONS. (2) To ______________ Order No. WD{Mr Wood/Mr Whitehead}51 (contd) Customer's No. ______________ standard coil, so we could not determine any advantage with this coil over standard. Unless there is some advantage from a production point of view we are of the opinion that for the present at-least we ought to continue using the oiled paper. We suspect that the paraffin wax becomes leaky at high temperatures and we are going to test a sample of pure paraffin wax to investigate this. Signed H.E.W. This Sheet must be filed on completion of the work. | ||
