"The" Simmons Gun Rib Co. in Kansas is one of the oldest and best sources of aftermarket vent ribs. They have been doing it since the, I believe, the 1930's. They did lot's of stuff for Winchester, including vent ribs on the model 21. I'm sure they do excellent work. I use Briley as I know they have fixtures and jigs that perclude any regulation problems and they are relatively fast. Best, Dr. BILL
