A.{Mr Adams} F.{Mr Friese} MARTINDALE Herewith is PD.339 which has been modified as regards the position of the ferrule holding the two halves of the shackle together, to give clearance for rear springs with interleaves. We believe the details have already been modified, but the drawing should now be re-issued officially. DA.{Bernard Day - Chassis Design} | ||
