Rolls-Royce Limited, Derby. For the Attention of Mr. H.{Arthur M. Hanbury - Head Complaints} E.{Mr Elliott - Chief Engineer} West. Dear Mr. West, I have your letter of the 16th instant concerning your further requirements of Sparking Plugs X399 for Bentley. I find that we have a small further quantity of these experimental insulators available and I am having a further dozen plugs made up and despatched to you as soon as possible: I hope to get them away on Monday next. Frankly, I would have preferred, before supplying any further plugs, to have had your detailed report on the performance of the first samples, because it might be that this report would cause us to make some small change in the plug design. However, in view of the urgency of the matter I am not letting this delay the despatch of these further plugs, but I do hope that you will let me have a report for our general guidance. You will recollect that when I sent you the first supply of these plugs under cover of my letter of September 1st, I told you that on high speed work these plugs might conceivably run you into a slight trace of pre-ignition; I am particularly interested in this possibility. Yours faithfully, N.F. STOCKBRIDGE, Managing Director. MAKERS OF AC SPARKING PLUGS - AC AIR CLEANERS - AC PETROL PUMPS - AC PETROL GAUGES - AC OIL FILTERS - AC OIL GAUGES | ||
