| -2- We would add that the felt used for the mats in the case of 25 HP., Bentley, and Ph.III cars is obtainable from J.R. Holbrook & Sons, Grosvenor Road, Coventry, andis made by the Coventry Felt Co. The material is 72" V.5 rubberised felt. It should be clearly understood that the amount of material as recommended is the minimum possible. A greater degree of silence will be obtained if all the body panelling including the rear boot, is lined with felt or Seapak material. This of course adds to weight and cost, and might with advantage be left to the discretion of the Coachbuilders. Hs{Lord Ernest Hives - Chair}/F.Dodd. | ||
