| To RHC.{R. H. Coverley - Production Engineer} x log# 35D Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}8/KW.5.10.34. SpectreCodename for Phantom III. We understand the rear and side steering tube is the same as on J-III, made to N.Sch.3907. From the feel on the road we think that either the springs are too strong or that the initial load is more than the 40 lbs. shown on the drawing. Will you please check this up and make sure that the ball is capable of a movement of at least .150" in either direction. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
