| ORIGINAL TO HS. {Lord Ernest Hives - Chair} FROM R. {Sir Henry Royce} R4/M18.11.25. Copy to RG. {Mr Rowledge} " OJ. " BJ. VALVES. Y3616 With reference to valves, in your Condor(Aero Engine) experiments with these, a pattern which did not prove successful was strange to us. We should however like a thorough test made of the umbrella type which Col. Fell has repeatedly told us behave so well in the larger sizes. R. {Sir Henry Royce} | ||
