| BY 1166 RECEIVED 1938 BY LA{L. A. Archer}12/T12.12.38 re. D.W.S. JACK PUMPS At the present time we are having trouble with Jack pumps owing to leaks through the release valve when this valve is closed. You will agree that this is rather serious, as when the car is jacked up, the jacks gradually give way owing to the leak on this valve. Two pumps have been returned within the last five days to the D.W.S. people with this complaint. I now have another one and I am retaining this in case you should wish to take this matter up with Mr Sessions himself. LA{L. A. Archer} | ||
