I know nothing about shotguns.
Friend died. He was almost 80. His wife didn't know he owned a gun. Had to get the furnace fixed and this gun was behind the furnace in the attic. She's guessing it hasn't been shot in 20 years maybe more? I can't figure out what model this is and what the value of the gun is. She could definitely use the $$ and doesn't want to completely undervalue the thing. By my research this could be worth $150 or could be worth over a grand depending on model, etc.
It is very light. From nose to tail it's right at 73 inches. I can't find a model number. If it will help, when I get home I can post the markings I can find. Gun is in very good shape.
Can anyone help?
