With regard to the specification sent you the other day for production Wraith III chassis, will you please note that the rear axle centre case and end plates are now held up as we are going to revert to the P.III type of breathing arrangements. This does not alter the castings or forgings but modifies the machining only. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
