I have an original Remington R51 for sell or trade. I got it from a friend who bought it years ago in rough shape. He had it gone through and blued. Not a collector piece but it looks pretty good is very accurate. It does have a failure to feed issue. I believe it is the 100 plus magazine spring. A piece of history. Let me know if you need additional pics or have questions. Open to trades, just let me know what you have.
