| 1332 EXPERIMENTAL DEPARTMENT. Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} 5/JH. 18th. January, 1939. Dunlop Rubber Co.Ltd., Fort Dunlop, Erdington, BIRMINGHAM. For the attention of Mr. Price. Dear Sirs, We are setting out on our test dynamometer to endeavour to find the power loss on various tyres. Figures we have at the moment lead us to believe that your racing tyres are more efficient than the standard ones. Can you therefore send us for test either 6½ - 16 or 6½ - 17, preferably the former, a pair of road racing covers and a pair of track racing covers. If we get any sensible figures from these we will let you have the results. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
