I have a 12ga 30" barrel I am trying to date. Serial is 16509 and is on barrel, frame and wooden fore piece. The main spring in a flat V. The side plate is stamped as shown. The gun would not cock and retain the hammer and someone had destroyed the screw head on the rod behind the butt plate. I drilled the head off and disassembled and made a new rod. I took the hammer and trigger apart and found the flat v stap spring not engaging the trigger properly. After reassembly (not so easy) it works fine. Any help dating this old girl would be appreciated. I am not sure if it is a champion as it does not look like the detail drawings online. Pics attached.
