I have a friend that has purchased a Remington 12 gauge pump-shotgun. He told me what he'd bought and I figured it was just an 870, but I went over and looked at it and I was stumped! It's definitely a pump, but it looks like it's built with the John Browning design. It bottom ejects, bottom loads, and it's not an old shotgun like the model 29 or model 10. It doesn't have a model number on it anywhere, I looked for a long time, although I didn't take it apart. It's in excellent condition, has a bigger forend like a modern pump, it's not a corn-cob forend. No choke tubes, and no case length designation. If you have anything that could help, please let me know.
