When fitting shock dampers on 40/50 chassis we should make them as near as possible to the dampers, which are about to be produced on production, which were issued under By/HEB.{H. Biraben}15/M2.2.33. So that any dampers which you are producing for 20-EX. or Bumper chassis should be brought as near as possible to By/HEB.{H. Biraben}15/M.2.2.33. When 19-EX. returns to England and before its next trip to France we shall require this new production 40/50 damper. Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} | ||
