Im buying a Winchester model 12 and the previous owner said its a model 12/25 lightweight 1040ish and I cant find any info on that one. Can anyone help me identify this? Also I was wondering if this is still a gun to hunt with or not. Im not a heavy collector but have a few nice guns and I am thinking of bird hunting with this one. Its choked modified and has plain barrel. And is it worth it to have a rib put on this or leave it be? I dont have gun yet if numbers are needed but can post when I get it. Thanks, Mike
