Dear Sirs, Will you please supply us with 3 A.C. bye-pass oil filters of similar type to the ones you sent us for trial some time ago. We should like full details regarding the most efficient 'set up' including size of inlet and outlet pipes, to what pressure it should be subjected and if it is important that the outlet be at a place of no pressure. We should appreciate your earliest delivery of the above. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
