Smith's Jacking Systems Ltd., Edgware Road, Cricklewood, LONDON, N.W.2. Dear Sessions, In the last few days we have had three cases in which a jacked up car slowly sinks down owing to oil leaking back through the pump. Two pumps have already been returned to you for your examination by our Test Department, and we should be glad to have your views on this trouble as soon as possible. Yours sincerely, | ||
