| To RHC.{R. H. Coverley - Production Engineer} from Rm{William Robotham - Chief Engineer}/Std. c. Hs.{Lord Ernest Hives - Chair} CHASSIS RADIATOR MATRICES. Will you please arrange to inspect all radiator matrices in future for (1) Accuracy of external dimensions - limits of ± .015 on the overall height and ± .025 on the overall width have been agreed upon by Messrs John Marstons and ourselves - we are arranging to have these limits put on the drawings. (2) Open-ness of waterways - Messrs Marstons are going to forward a gauge to us which is capable of being inserted in the ends of each waterway to check its gap. Will you also have all radiator matrices at present in stock inspected for open-ness of waterways and return any faulty ones to Messrs John Marstons Ltd. for correction.
