| -5- Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation}4/R.5.12.36. With reference to the "Corrujoint" gasket, we understand that the cost is considerably higher than a similar gasket in Copper and asbestos; especially the 3-ply "Sandwich" type of "Corrujoint". An example of the comparative cost is shown when this "Sandwich" type is applied to the standard production 4½-litre Bentley. We understand that the cost of the present production Copper and Asbestos gasket is 2/3d, while the "Sandwich" "Corrujoint" costs £1.7.6d. Rm{William Robotham - Chief Engineer}/CTS.{C.
