A customer brought in his dads old Mod. 11 16 gauge shotgun . It was left in a barn for way too long and is well rusted on the outside , but looks good on the inside . I need to know how to remove the bolt , so I can refinish the metal . He wants to give it to his son as a Christmes present . The only thing close to it is the Browning A-5 , that I have instructions for , they are alike up to a point (Bolt) . I checked Steves pages and found a parts schematic , but that's it . Any Help would be greatly appreciated ! Thanks !Mike
