| 1139 Experimental Dept. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}4/MH.{M. Huckerby} 10th. February, 1939. British Filters Ltd., Aircraft House, Market Harboro'. For the attention of Mr. T.Worth. Dear Sirs, We are returning under separate cover the filter case as enamelled in our works, which we anticipate you will use as a model. Additionally we are sending you the comparative oil samples between the "General" and "Fram" filters and would be obliged if you could give us an unbiased report on them. As you know we heard nothing further from the "Fram" people after sending them the first comparative samples between the "General" and the "Fram". Regarding the bridge strap we are getting this Nickel plated and will let you have it as soon as possible. Yours faithfully, for ROLLS-ROYCE LTD. | ||
