Da{Bernard Day - Chassis Design}/Sbr. 850 also 450. Is this necessary. Rm{William Robotham - Chief Engineer} B.111 and B.50. RE: STRENGTHENED PIVOT. On FD.{Frank Dodd - Bodies}273 herewith we shew the strengthened pivot, having a pin equal to that of Wraith lll. The boss on the yoke will not need increasing on B.111, but it will be necessary to increase it as drawn on the B.50 yoke piece. Opportunity of re-spacing the stud centres of the lower flange has been taken as requested some little while ago to improve the oil seal. FJH{Fred J. Hardy - Chief Dev.
