Dear Sirs, Some time ago, your Mr. Irving provided us with some 10 mm. plugs, type No. Y.7, having a reach of about 14 mm. Would it be possible for you to supply a further four dozen of this type? We would also like a set of 14 mm. sparking plugs, similar to your N.8 type, but for the reach, which should be 10 mm. longer. We require the latter for an experimental test, and would be grateful if you would provide us with a suitable type. Yours faithfully, | ||
