Wor.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Hdy.{William Hardy} RMC. SpectreCodename for Phantom III - D.W.S.Jacks. Herewith is N. Sch.4532, shewing the Phantom size of D.W.S. screw jack fitted to the SpectreCodename for Phantom III rear axle with an aluminium bracket similar to that used on Phantom. It is intended to use these until the hydraulic jacking scheme is ready. On Phantom the jacks come outside the petrol tank but this is not possible on SpectreCodename for Phantom III, and as a result the operating shafts are not as accessible as they are on Phantom.
