Mike,
Attempting to place a value on a drilling from the picture above is nearly impossible. When I look at a drilling or shotgun for possible purchase and evaluation there are about a hundred things I look at starting with the proof marks. I check the chambers and chokes with a gauge then inspect the stock and forend for any sign of small cracks. The condition of the bores is of high importance as well as the mechanicals. There are just too many potential issues. In the picture I can't even see the engraving (if there is any). A drilling like that can be worth as little as $700. or as much as $4,000. There is just too little information.
Regards,
Roger
