Bob, What is the serial # range and action type on the other F grade? I have a D grade in the 13XXX range with a small screw centered just ahead of the top lever. The action is unique among my Lefevers. Most have a stop which causes the top lever to stay to the right when the gun is disassembled, until you poke the post at the bottom of the doll's head slot to release the lever and bring it back to center. On my just mentioned D grade the action is silky smooth and there is no stop that holds the top lever to the right. It always smoothly comes back to center. No need to poke a thing. Very cool.
