| X3269 To EJJ. Hs{Lord Ernest Hives - Chair}/Smth.3/KW.10.9.34. Valve Spring Running Rig. In addition to the cams ordered for this rig in our memo. Hs{Lord Ernest Hives - Chair}/Smth.16/KW.5.9.34, we should also like one which will reproduce the Goshawk valve lift (Des.1739). We should like to point out the importance of designing the cams so that the durations of the lift and of the base circle are in the same proportion as on the camshafts as used in the engines.
