BENTLEY V SERVO SPRING PLATE.

For the first 300 cars being released, will you please alter the drawing GB.4069 to a phosphor bronze plate .012 thick instead of .016".

The overall depth of the plate should be altered to give a load of 4 - 6 lb. across the servo scissors to engage the friction disc.

We attach a load deflection curve of this disc to fix the above dimension.

The outer edge of the disc should be sealed with Heldite and adhesive tape.
