I was able to function test the lower fever makes her special yesterday. It is the subject of another post titled Lefever Embellishments. I find that the first barrel does not always cut when the shotgun is opened. Below is the best diagram of the action that I can find on the Internet. It appears that the cocking rod can be removed without removing the main spring. Removing and reinstalling the main spring is a major project. Actually three major projects. There is a special tool to remove the springs and a special tool to install them. So I would prefer not to disassemble this shotgun Do you agree that the cocking rod can be removed without impact of the main spring? Also, the diagram doesn’t indicate that there are set screws on the pin holding the cam in place. But my fox has them and I just wonder if there might be a set screw. Does anyone know one way or the other? I realize this is a relatively unique firearm and there may not be much history in this group. But any help is appreciated. I suspect I could get a specific answer over on one of the shotgun forums. But, I hate to join a forum just to ask a single question.
