| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c.c. to RJ. RG.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} EY. +7+1 RL/A51.3.27. SCRAPER RINGS. K.2103 K.741 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 hopefully constant. -R.{Sir Henry Royce} | ||
