We have been informed by G/Rb{R. Bowen} that N.Sch.4974 using a butted tube is the design to be adopted for adjustable side and cross steering tube ends, and that it will save approximately 6/- per chassis. Will you please apply this butted tube design to N.Sch.4967 and N.Sch.4968 already sent to you for Phantom III, but having a turned down tube. The diameter of the screwed forging will be slightly reduced. Ev.{Ivan Evernden - coachwork} | ||
