| -R. {Sir Henry Royce} FROM E. {Mr Elliott - Chief Engineer} C. to B.I. HS. {Lord Ernest Hives - Chair} BY. {R.W. Bailey - Chief Engineer} manifold. SECRET. ORIGINAL E2/M19.1.29. SS. {S. Smith} EXHAUST PIPE. X7230 We send herewith a blueprint of LeC. 2638., shewing a proposed cast exhaust manifold. We have endeavoured to make the manifold stiff enough to cause the end connections to slide on the cyl. block when the pipe gets hot. To do this we have modified the curves in plan and elevation. The side branches now pass above the sparking plugs 3 and 4. instead of below. The original of this drawing is attached to BY's copy of this memo. E. {Mr Elliott - Chief Engineer} | ||
