| To E. {Mr Elliott - Chief Engineer} X336 Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 2/KW.19.7.35 Spectre(Codename for Phantom III) Pistons. We think that as a safety-first measure we ought to design and make a Spectre(Codename for Phantom III) piston to exactly the same scheme as the present Phantom and 20/25 pistons. Mx. {John H Maddocks - Chief Proving Officer} reports so little trouble with these now that it seems foolish to start the car in production with anything else. In the meantime, our tests on semi-split pistons, etc., are going ahead. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} | ||
