| 5009 HOTEL DE FRANCE, CHATEAUROUX(French test region). Indre. France. GWH {George W. Hancock - Head Chateauroux} /HFH {Hoppy F. Hamilton} /4/JAB 10th December 1936. File To. Rm. {William Robotham - Chief Engineer} C. G. {Mr Griffiths - Chief Accountant / Mr Gnapp} W. H. {Arthur M. Hanbury - Head Complaints} Wyman. Do you agree with this suspension Rm {William Robotham - Chief Engineer} 22. G. {Mr Griffiths - Chief Accountant / Mr Gnapp} V. {VIENNA} It has been found that the pipe leading into the forward end of the main silencer has again broken off at the welded joint. This is the second time that this trouble has occurred, the last occasion was on 13.10.36. This failure seems due to the fact that there is not sufficient support, and that excessive stress is thrown on this point, and also at the bottom end of the down pipe leading into the first expansion chamber. Apart from expense, we can see no objection to fitting an additional suspension, secured to the tubular cross member which is conveniently situated just above the forward end of the main silencer. Rm {William Robotham - Chief Engineer} This is dealt with in other copy of this memo. [Signature] GWH {George W. Hancock - Head Chateauroux} /HFH. {Hoppy F. Hamilton} [Signature] | ||
