Rm.{William Robotham - Chief Engineer} HPS.{Horace Percy Smith - Experimental Factory Mgr} E/JNR.{Charles L. Jenner}1/HP.27.1.37. Phantom III Valve Spring Wedges. We send you herewith LeC.5494 showing a further design for preventing the oil from running down the valve stem. It will be noticed that this scheme does not depend on the wedges being butted together, the seal is formed by making the bore of the washer immediately below the wedges ~~made a close fit on the valve stem.~~ Drawing to BY.{R.W.
