Never did exist. It's a hardware store brand name on guns made by Crescent Fire Arms, Meriden, CT. or Janssen Fils & Co in Belgium.
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".
JANSSEN Fils & Cie LIEGE street Lambert le bègue, 4 then street St Gilles, 87 was rested by Joseph JANSSEN (Bench of test of Liege 1865/1897). This firm evolved in time by changing several times of corporate name, that is to say: JANSSEN Fils & Co (bench of tests of LIEGE 1895 - 1937) and rue Lambert Le bègue, 4 to LIEGE.. Etablissements JANSSEN Fils & Co S.A. (bench of tests of LIEGE 1937 - 1951) to LIEGE rue St Gilles,87. Fabrique d'Armes JANSSEN Fils & Co S.A. (bench of tests of LIEGE 1951 to 1954) rue St Gilles, 87 to LIEGE. This company deposited various trademarks of which: JF&C -CAMELLO - HANOVER ARMS Co - NITRO-STEEL - COLONIA LIEGE- ACIER PYROXYLE - JANSSEN SONS & Co - SOUTHERN ARMS Co - COSMOPOLITE.
Probably prior to WW 1. The .22 Velodog was replaced by the .2 LR and the .25 Auto cartridge. It is a pity, but "Janssen et Fils Co." at Rue Lambert-Le-Begué of Liege, Belgium only worked from 1893 to 1939; WWII interrupted business and after it, from 1946 to 1957 went under a low-activities period, closing since then. They made nice shotguns, rifles and handguns. Janssen et Fils Cie of course means Janssen and Sons Company.
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 & Fils, Leige, Belgium, c 1890-1915. Several million similar utility shotguns were imported US in this time period, few of any collector interest. It probably has large side hammers that are attractive to decorators and damascus or twist barrels that are probably no longer safe for use. Leaves a value in the neighborhood of $125-$150 as a mantle piece.
70-100 Years, 50-100 USD
I suspect this is a utility shotgun made in Belgium circa 1900 (+/- 15 years). Value will be determined by how nice it looks over a mantle, usually between $100 and $250. Janssen did make some higher grade pieces, so if you have fine engraving, checkering, and/or a silver plate for the owner's name, it could bring more, but not very much more.
Janssen Fils & Co if it has Belgian proofmarks or Crescent Fire Arms Co if it does not.
