| BI/NS.{Norman Scott} c. Rm.{William Robotham - Chief Engineer} ------ 346. DA.{Bernard Day - Chassis Design}6/G.2.4.38. LES PHANTOM III. REAR SPRINGS. Please receive herewith the following schemes :- F.CD.546 Rear Spring Aft Shackle. (Threaded Pins). F.CD.560 Front Anchorage Rear Spring. (Threaded Pins). The rear shackle scheme F.CD.546 shews new shackles required to take threaded pins. The rear dumb iron is also modified to take the larger bush size and provide a new rebound stop. The front anchorage scheme F.CD.560 shews a threaded pin and the anchorage bracket modified to suit. A new rear spring is required for use with these schemes with larger front and rear eyes and .600 negative camber. As regards the urgency of these schemes, they will have to take their turn.
