| ?/7/12 X361 Mr Barrington for Mr Nadin. Re Sheradizing of Exhaust fittings. With reference to the above it appears that from our tests that we should sheradize our silencers and bottom exhaust boxes as these appear quite satisfactory when treated in this manner, but the exhaust box attached to the engine should not be so treated. This confirms conversation I had with Mr Nadin on this matter. E.P. File Mr Royce admitted July 24. | ||
