I just sold this exact same gun in similar condition for a whisker off of his asking price - seller is in line with what he's asking. These guns are tremendous and an awesome addition to your collection.
The scope is worth 200 bucks. You will not buy a Weatherby .22 for 500 bucks in this kind of shape. I would say the package is worth 800.00. If you are not a collector just put the scope on e-bay or Gunbroker.com. It will bring from between 200 and 300 dollars. Look at closed auctions on both sites as that is what I did. Good luck with your sale. I used to have one and wish I had not sold it. Jeff
