| SG. {Arthur F. Sidgreaves - MD} From Hs. {Lord Ernest Hives - Chair} c. to Wor. {Arthur Wormald - General Works Manager} X 7230 Hs. {Lord Ernest Hives - Chair} 5/MJ.15.7.30. x7230 x7940 x7772 24-EX. EXHAUST SYSTEM. Replying to Sg. {Arthur F. Sidgreaves - MD} 13/D14.7.30. The exhaust system fitted to 24-EX. has not been standardised. Although it ran the 10,000 miles test on 23-EX. satisfactorily, we had certain doubts about it and therefore did not issue a standardisation sheet but fitted it to 24-EX. in order to get further experience. We have written to R. {Sir Henry Royce} saying that we think it is impossible to use aluminium on exhaust systems. Hs. {Lord Ernest Hives - Chair} | ||
