| -2- requested you to work. We are anxious, however, to know exactly how much extra the checking and testing etc. are costing us and also we want a figure for our existing matrices to compare with the new Mk.VI. matrices which we propose standardising. Will you therefore please let us have quotations for the following:- (1) 25/30. Radiator matrix to E.60931 in Mk.V. 58.MM. core with .006 tinned waterway strip and .004 tinned airway strip (as present standard) but with waterways, limits and flow tests as laid down by our Inspection Dept. (2) Bentley. Radiator matrix to EB.1798 in Mk.V. 58.MM. core with .006 tinned waterway strip and .004 tinned airway strip (as present standard) but with waterways, limits and flow tests as laid down by our Inspection Dept. Will you also please give us the increase in cost on Bentley and 25/30 due to - (1) Tightening up of external dimension limits. (2) Water flow tests for clearness of waterways. We would like you to clear up one apparent inconsistency in your letter of the 20th inst. AWD/BR/2 to our Order Office- you show a reduction of 2/3 by omitting tinning of the airway strip in the case of the Bentley matrix EB.3373, but show no corresponding reduction by omitting tinning of the airway strip in the case of the 25/30.HP. matrix E.61411. We should like to receive these figures as soon as you can let us have them in order to clear the Mk.VI. type of core for standardisation. We are today returning to you a Bentley radiator matrix which was tested on a car some while ago and appeared to be very deficient in heat dissipation - we would like you to examine and flow test it and see if you can suggest any explanation of this - it is of uncertain age. We are still awaiting your comments on the Ph.III. radiator matrix which had the bottom tank dip-soldered on by yourselves and which we returned for your examination. Thanking you in anticipation, Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
