| X719 Expl: Dept: Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}4/LG. 31st. Jan. 1927 Messrs. Ferodo Ltd., Chapel-en-le-Frith. Dear Sirs, For the attention of Mr. Field. We require some discs for a Hand Starter Clutch. These discs are always in engagement, working under light loads and the only slipping they have to do is when a back-fire occurs. The discs would have to work in a oily condition. The main feature required from these discs is a high co-efficient of friction. We should be obliged if you could tell us what material would be the most suitable for this purpose. We send you herewith a blueprint of the required discs. Perhaps when you have selected a material, you will let us know what these discs would cost per set of eight. Yours faithfully, | ||
