I found a Stevens double. It is not a 311 or similar models. I will try to describe it. Hammerless, It uses a rib extension for lock up. This differs in that the extension has a square hole, ala LCS, FOX etc. I don't think it uses a rotary bolt to engage, maybe a through bolt? There is some modest engraving on the action, not badly done. The bottom of the action is marked, J Stevens Arms and Tool Co. Chicopee Falls Mass. Krupp steel barrels. The gun is solid but not as heavy as a comparable 311. Any information would be appreciated.
Thanks
Rick
