If there are any experts out there in very old W. W. Greener side by sides I would like to send some photos for help ID'ing mine. It has been in my family at least 100 years and is a 10GA exposed hammer side by side. Not a real fancy gun but there is some engraving. On the rib between the barrels it says "WW Greener St. Mary's Works Birmingham Macnab & Marsh Canadian Agents" I have had others guess and am now looking for someone who may want to guess but knows more than the past contributors
