| X7941 Too Hs. {Lord Ernest Hives - Chair} From GWH. {George W. Hancock - Head Chateauroux} Hotel de France, Chateauroux(French test region), France. 9.2.33. 19 EX. We have after getting the normal load right on the dampers, i.e. 40 lbs. been checking up the progressive loads. The front O.S. damper was not progressing after 85 lbs was reached. We found the trouble was the valve sticking being too tight on the stem. The following figures are the progressive loads. FRONT.
