| E - Poetic, Honomy? To EH. from E.{Mr Elliott - Chief Engineer} ORIGINAL E5/B13:6:17. 5 X 2209. X 2369 X 2809. X 2749 Re Pistons. We have been previously informed by you that multi-ring pistons are good for slow running so far as chassis work is concerned.. Would you kindly note that Mr. Royce would like to know if these same pistons have the additional virtue of not oiling up during a nose dive from a high altitude on aero engines.
