Roy, they ae a nice gun. I have one in 16 ga. that has 2 9/16" chambers and 30" Krupp steel barrels. It has the same markings as yours on the bottom of receiver.
If yours is like mine, the hinge pin has a cover plate that is screwed on, take it off and the hinge pin is also slotted to remove easily. In the front of the receiver there is a set screw that holds the hinge pin in placve, loosen it and you can rotate it if you gun is off the face. Then just use a drill to spot another hole, replace set screw and put hinge pin cover on.
Mine also has a monte carlo stock, side clips and Greener type cross bolt. Plus it weighs 6 lbs. 1.8 oz with a Pachmayer recoil pad, which I don't care for.
How bad can that be for an inexpensive but well made gun.
