| Der. c. Rm.{William Robotham - Chief Engineer} E.V. 200 B. 446 E.9/HP.11.2.37. Bentley III Suspension With regard to the torsion bars for the above suspension, I still think that we cannot allow these to hold up the front floor. The Vauxhall Co. have got away with very short torsion bars on their 25-HP. model, and I understand from Hs.{Lord Ernest Hives - Chair} they make these stand up very successfully by using a final shot blasting operation. I would, therefore, like to know how the stress in our torsion bars compares with the Vauxhall practice assuming that ours are cut short enough to avoid holding up the floor level.
