I have in my possession and possibly for sale , a Browning Superposed 12 bore 30 inch with both full choke and a stepped 8mm vent rib ,double trigger . The barrels are marked Fabrique Nationale deArms de Geurre Herstal Belgique , and the letters FN on the top lever .Nowhere on the gun does it say Browning . The serial number is 31 . Browning UK had the gun on show at a CLA Game Fair some 20 years ago having confirmed that it was genuine and at the time was the oldest know gun in existence .
The gun is in good overall condition but has been lightly refinished ,apart from a recoil pad is all original .
How do you value a gun like this ?
