| To Rm{William Robotham - Chief Engineer}/IMW{Ivan M. Waller - Head of Chateauroux}, from Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} Hotel de France, Chateauroux, Indre, France. 4079 Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}4/MH.{M. Huckerby}28.7.39. 14.B.V. STEERING. Thank you for your memo of 25th. The roll centre theory does not appear to be the explanation of your trouble. We are sending out to you the following parts. (1) 1¼° yokes and pivot pins removed from 7.B.V. (2) Pre-increased tyre clearance cross steering levers for use with 1¼° yokes. (3) Pivots and hubs ex 7.B.V. with old geometry cross steering levers fitted and also suitable for use with levers under (2) above. (4) Old geometry centre steering lever with cross and side steering tubes ex 7.B.V. (5) 7" deflection rear springs. (6) Production front roll rod. (7) Bendix casterometer as requested. A fitter is going to Chateauroux in approximately 10 days' time. We suggest the following programme of tests:- (a) Test 1¼° castor with existing geometry by fitting yokes (1) pivots and hubs (3) and levers (2). (b) Test old geometry with 1¼° castor by fitting levers (3) and parts (4). (c) If there is no improvement from any of these changes, revert to steering parts exactly as now and fit 7" deflection rear springs. (d) Fit production roll rod.
