| -2- RM{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}1/AP.16.1.37. Item 7. Bentley aluminium drums run at 3/7ths. the temperature of standard Bentley drums, and the grease in the hubs is not melted. Ph.III. rear drums especially get very hot, and we could not agree to the omission of the grease catchers without extensive testing. Item 8. We have no objection to this if it runs in France.
