| 1280 Rm {William Robotham - Chief Engineer} /Std.3/AP. 30th September 1937 Messrs John Marston Ltd., WOLVERHAMPTON For the attention of Mr.Dunn Dear Sirs, Confirming our telephone conversation of today with Mr.Dunn, the code numbers of the Mk.VI. radiator matrix units returned to you as faulty were E.48.W. (tank which we have here) A.72.Z and N.68.N. We would very much like to know if possible which of the matrices refer to which number i.e. we have here two matrices which Mr.Dunn brought over, one having been flow tested and found satisfactory, the other untested. We would like to know which is the code number for each of these matrices (in other words, which top tank belongs to which matrix?) Finally, we would like you to flow test the third matrix which is at your works (dislodging as little sediment as possible) and let us have it back, together with its code number. You will remember that Mr.Dunn promised to send us a silted up Mk.V. matrix unit, complete with top and bottom tanks - one that has been returned for reconditioning - so that we can make some further tests with a view to clearing it. We do not expect to have the ten Ph.III. oil coolers for conversion purposes until about the middle of next week. We are returning to you herewith the Ph.III. radiator matrix (.005 tinned and .003 untinned) which ran on our last 15,000 miles car in France (you inspected same while at our works) and would particularly like you to test this on your dissipation plant to check whether its effectiveness has been impaired by the insects, dirt, etc, which it has accumulated. We want to use this as a check on our tests on the car itself. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
