F. Dumoulin & Co was a Belgian gun maker located at 2 Rue de la Fontaine Liege, Belgium from 1894 to about 1930. Please check that serial number one more time as the serial number-year made table in my reference book only goes up to number 49,501+ for 1930 for F. Dumoulin made hammer doubles. Value of any old shotgun is determined by the guns condition, the amount of original finish remaining on the metal and wood and the mechanical condition as well as the construction. Many Belgian makers were using damascus barrels as late as 1935.
