Hs{Lord Ernest Hives - Chair}6/LG19.7.20. X.3793 PRESSURE GAUGES FOR AMERICAN CARS. We have received a further two Pressure Gauges from America with the scale modified as we suggested from the first two gauges we received. Unfortunately the air pressure gauge we have just received is in a damaged condition - the hand does not go back to zero - it stands at 2 lbs. pressure under normal conditions. We have no doubt that these gauges will work satisfactorily - the mechanism is quite sound. A point we think could be improved is the appearance of them. We suggest that the appearance of the gauges would be improved if the scale had silvered instead of white letters, and that the needle was also treated in this way. So far, we have only run the oil pressure gauge on a car - we have not yet received a satisfactory air pressure gauge. Hs.{Lord Ernest Hives - Chair} RECEIVED JUL 31 1920 | ||
