She's Belgian with German barrels. I can't tell you her name, but I can give your some measurements. She is chambered for 2 3/4' shells with a chamber diameter of 0.736" (tight for a 16 gauge). Her bores are 0.673" right and 0.665" left and she's choked 0.032" right (Full) and 0.024" left (Improved Modified). The barrels weigh 2.52 pounds and she was made in 1950.
The manufacturer could be Dumoulin, who is still in business, Janssen Fils & Cie (1888-about 1956), Anciens Establissements Pieper (1859-mid 1950's) or one of the other Belgian makers, even FN.
