What is the value of a Janssen shotgun?

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.
