What is the value of a pre World War 2 browning superposed shotgun with two sets of barrels with matching serial numbers 5310?

Superposed shotguns are very collectable when in top condition. Values have a wide range due to so many variations and grades of the Superposed and other Browning Over/Unders. Value is too difficult to be accurate without seeing the gun. Condition which includes the amount of original finish and original configuration will determine value. Your gun especially would be difficult to quote. A 2 barrel set made in 1933, is highly prized in top condition because of the dual serial number barrel sets. Recommend taking it to a gun shop for appraisal.
