I finally got some pics taken of my Lefevers. Sorry they are so large, its better to see the detail. I was mistaken on my serial numbers. My guns are:
10540 F on frame 10540 E on Barrels 10ga 31"
11642F on frame,11642 on barrels 10ga 29 7/8" Stippeled top, Notice the concave shape from the rib comes back over the top clear back into the lever,unlike 10540. This is especially nice.
These two guns have the following adjustable parts:
Adjustment in the forend that contacts the cocking rods
Forend lug adjustment to push the forend into the action
Screw in barrel lug to wedge the lug wider
Screws to adjust triggers
Bushed firing pins
Screw to turn automatic safety on and off
Screw to put more pressure on the top bolt if lockup is loose
