H. Coverley - Production Engineer} --------------------- 20/25 Servo Friction for Balance Arm. N.Sch.4453 herewith shows the Bentley disc type friction device applied to the 20/25. The balance arm is the same as for the Bentley (N.Sch.4457) and as this is shorter than that of the present 20/25 the levers are rather higher up than now, but the balance lever unit is unaltered except for a new lever for the air damper which is the same as the new lever that is required for the Bentley.
