X.3076 Re Piston Rings.

Will you please make an experimental run with piston rings so worn or arranged that the gap in the split is wide, and will you arrange for part of the pistons to be pinned in our usual order, and part of the pistons to have the pinning of the rings commencing with the top one on the opposite side to the standard.

(See copy of my memo R5/B9:6:17 to By.{R.W. Bailey - Chief Engineer})

Ymp R.{Sir Henry Royce}
