| To ROY.{Sir Henry Royce} From Hs{Lord Ernest Hives - Chair}/Tan. X5300 Hs{Lord Ernest Hives - Chair}/Tan.3/MJ.31.12.29. 20 HP. CLUTCH FRICTION MATERIAL -G.54043. Two of the above are on order from Messrs. Ferodo, for Expl. purposes, we believe. The specification calls for moulded on material. Our experience has been that the rate of wear with this material is inordinately rapid, and as Mr. Field of Ferodo's was here yesterday, we requested him to make these of ordinary rivetted on Ferodo fabric rings, instead of moulded material. Copy of our confirmatory letter is attached. Hs{Lord Ernest Hives - Chair}/Tan. | ||
