Hanbury - Head Complaints} c. to Hs.{Lord Ernest Hives - Chair} ------------ ROY{Sir Henry Royce}8/MGS.7.34 ---------------- Radiator Matrices Further to our recent discussion regarding improved manufacturing methods for the supply of Marston Matrices Type Mark III, Messrs. Marston state: "Our experience indicates that the tinning of the metal forming the waterways is advantageous and we are "making arrangements for the Matrices to be supplied in this "manner"." and for this additional tinning they are suggesting the following charges: Bentley......... 4/10d 20/25 HP........ 5/8d 40/50 HP........ 8/1d I think we are all agreed this is necessary, and we are instructing Marstons to proceed accordingly. As far as Mark V Type Matrices are concerned, they despatched the first 70 mm. experimental matrix on July 2nd, the metal of the waterways being .006" tinned strip, and the metal of the airways .004" also tinned. The reason that these are both tinned is to ensure tinned metallic contact between the airway and the waterway. They were hoping to despatch the 58 mm experimental Mark V Matric yesterday.
