I have a double barrel shotgun that is marked AD Jansen Fabricant D' Armes no one barrel and DE S.M. Le Roi. Bruxelles, it's very nice, is engraved, double triggers with ejectors, nice chekering, 12 Gauge, straight stock and is marked 2 in gold on the lever and the rib of the barrle near the reciever. The gun is in very good condition, with plenty of case color and blueing is very strong - Looks like it's seen very little use. I'd like to know what exactly it is and approximate value. Any info would be greatly appreciated.
Thank you,
Scott
