| To BY.{R.W. Bailey - Chief Engineer} from E.{Mr Elliott - Chief Engineer} c. to BJ. Hs{Lord Ernest Hives - Chair}: X8090 E1/M4.10.27. SPORTS PHANTOM - PISTON IN 'Y' METAL ALLOY. X4004 We send herewith Lec. 2467 shewing the above drop forged piston. You will see on the drg. where we intend to machine the piston inside. There is a trepanning operation combined with an undercutting operation required for forming the piston pin, pedestal bosses, and skirt.
