Flow Testing of Gauging of waterways of Radiators matrices - all chassis. Further to our Rm {William Robotham - Chief Engineer} /Std.7/MH. {M. Huckerby} 22.9.38. and Rm {William Robotham - Chief Engineer} /Std's. discussion with By. {R.W. Bailey - Chief Engineer} we have written Messrs. Marston: as per attached copy letter, and would like you to keep a record of results covering approx. 200 chassis. We think that it will be sufficient to check the matrix waterways with a gauge as in the past and leave flow testing of the matrix to Messrs. Marstons since we have never carried that out here. We suggest that matrix units checked by the works should have a small brass disc sweated to the bottom tank with the letters 'RR' stamped on it, signifying that it has been checked at R.R. Ltd. In this way if any defect develops in a matrix in service it will be possible to determine whether it is attributable to the tank being removed and hand soldered to the block instead of being dipsoldered, and will avoid any argument as to whether the defect is RR's or Marstons' responsibility.
