| 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 - 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.
