| To E. {Mr Elliott - Chief Engineer} c. to Wor. {Arthur Wormald - General Works Manager} c. to By. {R.W. Bailey - Chief Engineer} X5040 Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 11/KW.13.11.34. 20/25 HP. Pistons. It will be recalled that the Bentley piston has a longer skirt than that at present fitted to the 20/25. We think that this is a better piston from the point of view of life and freedom from cold knocks, and we are running this piston on the present 10,000 miles test on 21-G-IV. We would recommend that these pistons are standardised on the 20/25. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} | ||
