| X8350 Hs. {Lord Ernest Hives - Chair} BY18/H. 14.12.25. NEW PHANTOM(Codename for PHANTOM I). REAR AXLE. Just a reminder that on the New Phantom(Codename for PHANTOM I) axles running on the experimental test, I believe we have got the 57" track. We have ordered material in such a way that we can make the 57" track at any time, as soon as you have got the Standardization Sheets through, and providing we give the Works just sufficient time to change over from one type to the other. I believe R. {Sir Henry Royce} is rather anticipating us getting the wider track on quickly. BY. {R.W. Bailey - Chief Engineer} | ||
