[Handwritten: 1332] Dear Sirs, Confirming the writer's discussion at Derby regarding contact areas of new and worn tyres, we attach copies of diagrams in respect of 6.50-17 F4T 'C' type tyres. We used for the worn tyre one of those samples which you returned to us for examination in respect of short mileage, on which we have written you under separate cover. It is interesting to note that our anticipated results are confirmed by actual tests. Yours faithfully, FOR THE DUNLOP RUBBER CO.LTD. [Signature] Manager, Car Manfrs. Division.
