value of 12g fox sterlingworth

Question
I, like a lot of others, have been handed down family heirlooms.  In this case it is a Fox Sterlingworth 12g.  The gun is a double barrel, side by side, with the matching stamped numbers 62053.  This was a well used weapon by the looks of it and shows some wear on the butt plate and foregrip.  All I really know about it is that it originally belonged to my grandfather.  If you can provide any information on this particular weapon, it would be very appreciated.

Answer
