| 1280 Rm {William Robotham - Chief Engineer} /Std.16/AP. Experimental Department 15th June 1937 Messrs John Marston Ltd., WOLVERHAMPTON For the attention of Mr.Dunn. Dear Sirs, We are making the necessary arrangements for our Repair Dept. to handle the routine of returning any silted up Mk.V. matrices to you for renovation. We should like you to fix on all renovated matrix units a small plate, with R.C. (replacement core) stamped on it, to the rear face of the top tank on the left side of the piece number which is fixed there, so that we can distinguish reconditioned Mk.V. cores from any others. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
