Ok I need help. I have a Pirotte Et Fils stamped shotgun which is also stamped Liege and made in Belgium. It is a 12 gauge sxs sidelock ejector and has a Triumph stamp underneath. It is in very good condition about 90% and seems to be of a higher grade then the Pirotte I have located on the net. The receiver is a silver and has 3 ducks flying over a marsh. The closest I see to it on the net is a Centaure royal crown grade sxs. The side plate is identical. Serial number is 29xx on the Pirotte. If anyone can help I would be grateful.
