I have a Jansenens & Son's 12 guage double barrel shotgun with steel barrels at least fifty years old. How could I find out how much it is worth?
Janssen & Sons Co.
From the wonderful site about Belgian gunmakers at littlegun.be we find the following:
JANSSEN Fils & Cie
Address: Lambert le bègue, 4 Liege
Moved to: St Gilles, 87, Liege 1865/1897.
This firm name evolved over time:
JANSSEN Fils & Co (LIEGE proof books 1895 – 1937) and rue Lambert Le bègue, 4 to LIEGE..
Etablissements JANSSEN Fils & Co S.A. (LIEGE proof books 1937 – 1951) to LIEGE rue St Gilles,87.
(S.A. means "Incorporated"
Fabrique d’Armes JANSSEN Fils & Co S.A. (LIEGE proof books 1951 to 1954) rue St Gilles, 87 to LIEGE.
This company used various trademarks including:
JF&C – CAMELLO – HANOVER ARMS Co – NITRO-STEEL – COLONIA LIEGE - ACIER PYROXYLE – JANSSEN SONS & Co – SOUTHERN ARMS Co – COSMOPOLITE.
Janssen made a variety of guns which could vary from cheap and poorly made to excellent. Depending on which one you have, and its condition, your gun could have a value between $50 and $800.
See for example this one offered by Dixie Gun Works for $795. http://www.dixiegunworks.com/product_info.php? cPath=21_157&products_id=12072
However, note that gun is in good condition, in its original box, with its original accessories.
MOST Janssen guns are going to be worth FAR less.
Also, because Janssen dates back as far as 1865, there is a chance that you have a damascus barreled gun. If so, its value is only decorative as a wall hanger.
On the other hand, Janssen built guns right up to the 1950's, and those are modern and completely shootable.
If you want to know more about your gun, you're either going to have to take it to a shotgun expert, or you're going to have to take good close up photos of the gun
take overall photos of the left and right, closeup photos of the left and right of the receiver, remove the barrels and take close up photos of the underside of the barrel and of the flat of the receiver and of the bvtt plate your shoulder would rest on if it has any marks on it at all.
When you take your photos, include a tape measure or ruler.
