Anyone know what one of these are worth? The gun is in pretty good condition but could use some sanding and stain/oil. Its not rusted nor is the wood beat up, just getting dull/fading on the wood. It is an old lever action 30-30 made by Sears Roebuck and CO. A friend of mine has it and offered it to me for $140 or offer. Just curious to what its worth. I probably wouldn't use it much but would look good in my gun cabinet. Any ideas would be helpful.
