| 6153 Rm{William Robotham - Chief Engineer}/Wst.2/JH. 4th January, 1937. The Philco Radio & Television Corporation of Gt. Britain Ltd., Perivale, Greenford, Middlesex. For the attention of Mr. A.F.D.Knight. Dear Sirs, We are now able to give you a report on the new type L choke sent to us under cover of your letter of 9th Nov. last. We find this choke to have very little effect in surpressing ignition noises and not as good as a surpressor. We are however leaving the choke on the chassis in order to give it a more extensive test. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
