DERBY Gentlemen, For attention of Mr. Hives. We are in receipt of your letter of the 1st August and have noted your criticism of the No.611 plugs. The six plugs which you are returning for our examination have not yet arrived, but as you require something to withstand rather more heat we have put in hand immediately thirty of No.610. The No.610 is of the same external dimensions as the No.611 and will be provided with a special electrode end to suit the terminals which you are using. As a result of our own tests we are satisfied that the No.610 stands distinctly more heat than the No.611. As soon as the six No.611 plugs arrive we will examine them and write to you again. Yours faithfully, p.p. K.L.G. SPARKING PLUGS LIMITED. [Signature] Managing Director | ||
