| Rm{William Robotham - Chief Engineer}5/R.{Sir Henry Royce} 1139. 25th October, 1938. British Filters Ltd., Aircraft House, MARKET HARBOROUGH. (For the attention of Mr. Worth.) Dear Sirs, Thank you for your letter of October 24th. We are quite satisfied with your filters as a result of the tests we have been carrying out during the past six months, and, at the present time, one is on the point of completing its standardisation tests on the Continent. We are still, however, waiting to hear from you regarding the price at which you are prepared to supply production quantities. We were recently talking to Commander Du Cane of Vosper Ltd., Portsmouth, and as he appeared to be unfamiliar with the by-pass type of filter we mentioned your product to him as being suitable for his Marine units. Possibly you will find it worth while to follow up this enquiry. Yours faithfully, For ROLLS-ROYCE LTD. | ||
