| To BY.{R.W. Bailey - Chief Engineer} from EH. x.3547 EH2/LG8.9.19. With reference to Pressure Gauges supplied by J.{Mr Johnson W.M.} Benson Ltd., we recommend that you ask these people to submit Pressure Gauges with a black finish which we require; we think then, we might be more favourably disposed towards them, if they could give us a better black finish than we are at present getting from Salters.
