As requested by memo Rm{William Robotham - Chief Engineer}/Les.1/JH.21.12.37. we have prepared a scheme to provide the RR. Shock Damper with large replenishing valves. Accordingly, we forward you herewith one blue print of the following :- S.CD.314 Replenishing Valve for Shock Damper. The following parts have been detailed to suit, and attached are two blue prints of each (3 of part marked @) :- @ EX.S.354 Piston for Shock Damper. 4 off. EX.S.355 Spring for Piston - " 4 off. EX.S.356 Bolt " " 4 off. The following existing parts will also be required :- EX.S.308 Spring for Replenishing Valve. 4 off. EX.S.309 Ring " " " 4 off. EX.S.310 Valve " " " 4 off. EX.S.311 Washer for Replenishing Valve. 4 off. K.4460 Washer for Replenishing Valve. 4 off. KB.1803 Rivet " " 4 off. The following parts will not be required :- F.59293 Piston for Shock Damper. 4 off. F.59285 Bolt for Piston. 4 off. F.59278 Spring for Piston. 4 off. F.59286 Spring for Replenishing Valve. 4 off.
