I figured I would ask her because there’s more traffic. I just bought a 20 ga semi auto sears and Roebuck “Ted Williams” edition. It has mod 75 20 ga 583.7500 stamped on the barrel. It has a selector switch on the end of the fore end. With an H and L. I took the fore end off and I can’t tell the switch does anything. Anyone have any ideas?

I know it’s made by High standard and it’s a supermatic deluxe.
