| 1305 EXPERIMENTAL DEPARTMENT. Rm{William Robotham - Chief Engineer}/HFP.5/JH. 23rd.August, 1939. Toledo Woodhead Springs Ltd., Toledo Spring Works, Sheffield.1. For the attention of Mr. Woodhead. Dear Sirs, We thank you for your letter of August 19th. agreeing to carry out tests with graphite impregnated Tufnol interleaving. We regret to have to inform you that at the moment this can only be produced in sheets 26" x 36" consequently it will be necessary to join lengths together for the purpose of interleaving the springs. We should be very much obliged if you would let us know the width of the spring which you intend to use for these tests so that we can instruct the makers to cut the sheet accordingly. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
