| Mr. Hives from GWH. {George W. Hancock - Head Chateauroux} X.3525 X457 9.11.22. TESTS ON DELAGE CAR FOR WOBBLES. X.3525 Tests were carried out on this car in the condition as it arrived. Wobbles could be obtained at a speed of 22 k.m.hr. but were not of a violent order now could they be kept for any considerable distance. After having the front tyre pressure increased to 60 lbs., wobbles of a fairly violent nature could be got easy and could be kept up for considerable distances. The wobbles were kept up to a speed of 42 k.m.h when they quickly disappeared. The speed of the wobble will be checked. GWH. {George W. Hancock - Head Chateauroux} | ||
