[text is struck through] GRY{Shadwell Grylls} P.2. S.M. 2nd Gearbox. N.Sch.4128 herewith gives particulars of weaker selector rod springs which we should like tried to reduce the friction when the balls are lifted. These springs will give approximately the same locating force as was obtained on the pre-synchro mesh boxes. HDY.{William Hardy} | ||
