| K5704 To Ev. {Ivan Evernden - coachwork} from Hs {Lord Ernest Hives - Chair} /Lid. {A. J. Lidsey} C.c. E. {Mr Elliott - Chief Engineer} By. {R.W. Bailey - Chief Engineer} Hs {Lord Ernest Hives - Chair} /Lid. {A. J. Lidsey} 12/KT.16.11.33. SIDE SPARE WHEEL CARRIER - VULTURE(Experimental 6 CYL OHV LONG STROKE / Aero Engine) - EV {Ivan Evernden - coachwork} 5/TH.15.11.33. The 1 1/4 diameter tubes on 1.J.3. are, we consider, sufficiently rigid; there is a little flexibility (less than 20/25 HP and P.II) but it does not warrant larger diameter tubes.
