I am trying to restore my grandfather's Field grade, 12 ga. The stock is old and dry rotted. Somewhere in time, the two screws that hold the forend iron onto the splinter forend were lost. The screws are about 0.75 inches long (measured from an Ideal grade, 20 ga.) or 1.1 inches long (from a Trap grade, 12 ga.). I can provide other measurements. Can I buy these from some supplier? Who? Jack First and Numrich Arms do not have them.
