| X.2925 EH/AT23.5.17. X. 2925E - IMPROVED VALVE SPRING WASHERS FOR "EAGLE" TO LEC. 744 ------------------------------------------------------ These have been fitted to an Experimental engine. They are the same weight as the old ones but very much stronger. These washers are now being fitted to standard engine-s. We consider that the "Falcon" valve washers might be gone over to see whether they could be improved in the same way. These will be issued from D.O. to-day. E.T.C. EH. | ||
