| -3- the rear roll rod which was clearly the major cause of the trouble. Fig.2 shows three curves given us by Olley. Of the first two, (1) The La{L. A. Archer} Salle 1936 and (2) The Oldsmobile 6 1936, he writes "The direction of curvature of the steering angle line above .4g is profoundly important. Downward curve means a rear skid and is dangerous". "A sudden downward curve like the La{L. A. Archer} Salle and Olds.6 is due to too much rear stabiliser and is to be avoided". (3) is reproduced from a sketch in another letter and is described by Olley thus - "The cock-eyed condition produced by too much rear stabiliser would be condemned in any country."
