Lidsey} n66 Da.{Bernard Day - Chassis Design}1/HP.7.5.37. Phantom III Herewith LeC.5650 shewing the D.W.S. standard Jack pump fitted to the Phantom III chassis We understand it is intended to introduce this on production on "D" series. The drawing shews the standard R.R. trap-door. A further drawing will be sent shewing the D.W.S. standard trap-door, but as this involves modification to the floorboard pressing, it is not intended to wait for this before introducing the pump. Will Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} please rig up the pump on an experimental Phantom III to check up the mounting and operation. It will be noticed that there is a small modification to the standard pump, consisting of the position of the handle relative to the piston centre line.
