| TO HS.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} (At Le CanadelHenry Royce's French residence.) [Struck through: Copy to DJ. RG.{Mr Rowledge}] [Struck through: E.{Mr Elliott - Chief Engineer} BY.{R.W. Bailey - Chief Engineer}] ORIGINAL SCRAPER RINGS. X 2103 [Struck through: X741] R1/M31.3.27. REC'D & DESPATCHED FROM WW. 4.4.27. We don't want to be dependent on L. shaped rings on either cars or aero engines. There is the ring known as the perfect circle, and there is the straight-forward practice. Compare these two with horizontal and upward looking holes. We must have something which is hope- fully constant. R.{Sir Henry Royce} | ||
