| To EY. Copy to Mr. E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Dep. RHS. XN 1 HDY{William Hardy}/2/MN.16.4.35. R.J.H BENTLEY Servo-friction for Balance Arm. N.Sch.4457 herewith shows slight modifications to the scheme previously sent for this (N.Sch.4406) in order to allow of the same balance arm being used for the 20/25 without alteration. The length of the arm is slightly increased and we are not able to use the existing lever for the air damper so this has to be a new piece. HDY.{William Hardy} Att: N.Sch.4457. | ||
