Hardy - Chief Dev. Engineer}3/MH.{M. Huckerby}23.5.39. B.V. STEERING. We have recently standardised a castor angle of ¾° for the 300 B.V. chassis. we wish to fit this to our experimental chassis also. Will you please prepare the necessary yokes FB.4305/6 for chassis 10.B.V., 11.B.V., 12.B.V., 14.B.V., and 4.B.50. Levers FB.4873/4 should be fitted at the same time. Existing yokes with small diameter pivot pins will modify to the new angle. Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} | ||
