"According to a list I have, your gun was made in 1928. Its very hard to predict what it might be worth. I would go to gunbroker.com and look up Fox Sterlingworths. They usually have any number up for bids and you can look for one similar to yours to get an idea of what they are going for. Don't worry about early bid prices. The auctions usually close up in the last hour or so." Quotation from shooting sportsman forums.
