Rm{William Robotham - Chief Engineer}/JD.{J. Draper - Frames}2/ET.3.12.40. 727 1030 MYTH FRAME. ---------- Please receive herewith the original of PL.419, Rear Bumper Stop. We have shewn the rubber moulded on to a metal plate and bolted to the underside of the frame. It is we believe necessary to have a simple angle stiffener on the inside of the frame, due to its light gauge. Ev{Ivan Evernden - coachwork}/JD.{J.
