Janssen Sons & Co. was a Belgian (Liege) gunmaker from the early 1890s through approximately approximately 1931. The Damascus shotguns were imported early on, but importation stopped due to WW-I in 1914.
Because of the low grade steels in the guns, their value is very low - $100-300, depending on condition. Firing them is contraindicated, unless the shells are the original short (2 1/2- 2 5/8 inch) shells with black powder loads, and the barrels have been inspected by a gunsmith.
Basically, they're mantlepiece display weapons.
Janssen & Co, Leige, Belgium became Janssen Fils & Co., c. 1892. Sometime between 1895 and 1914 the company became part of Simonis, Janssen, Dumoulin & Co. They would have marked guns intended for export to the United States "Sons" instead of "Fils".
Probably about $125-$150 as a mantle decoration.
Janssen Fils & Co was making guns from 1895 to 1965. Since yours is marked in English (Sons instead of Fils) it was made for export to the US and the mass import of shotguns from Belgium was cut off by WWI and never resumed after, so it's a pretty good bet that yours was made between 1895 and 1914. Value will be determined by how nice it looks over the mantle, usually $150 to $250.

Janssen was a Belgian gunmaker. According to my notes, the company used this name c. 1892 - 1896. Answer I have a Janssen Sons shotgun that used to belong to my grandfather. It has carving on the side of the breech and the bottom. It also has carvings on the walnut stock. I was given this same gun from my father. It has very detailed carvings in the stock and etchings on the barrel. I have been unable to find out anything about the maker or a present day price. I have looked in many of the shotgun books. My father paid 50 cents for this gun during the depression.
He has one daughter, Stephanie.
Kris and Stephanie from Sons of Guns do not have kids. Kris met Stephanie at a party in 2009, where she offered him an apprenticeship at Red Jacket.
