I found one at: html//www.cabelas.com/gun-inventory---scarborough---english-sg---932981-wcsct-sca.shtml, I just ran a Google search for W & C Scott shotguns, and it was about the 8th one down the page. Similar to mine but again the firing pin screw is different. This is the closest lock to mine I've seen yet. The forward edge just in front of the hammer is curved though like tanky's whereas mine is angled. This one is suppose to be 1882. I wonder if they used different locks thought the years.
