| 1025 + 666 + 642 To By/Ald.{F. Allwood - Experimental Design} Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}2/JH.21.5.39. Rear Dampers - Wraiths. Will you please design and instruct rear dampers of the Gordon-Armstrong type. These are called for in the specification of 31,32 and 33.G.VII. The dampers are to be in front of the rear axle, so that the links may be cheap. The dampers should have twin valves as these are cheaper than single valves. The dampers should be cam-operated self hardening with selector control to the column. No pump unit or bellows will be required, but the pump will be left on the cars in case we need them.
