Some of the most beautiful work of this craftsman, and many others, are in this book “Liège Gunmakers through their Work. 1800 - 1950”.

Here is a folding rifle in calibre 28, marked JF in a rhombus, more than likely for Janssen Frères. A lot of folding rifles have been made with a "snake key", a snake-shaped opening lever on the right.

This one, on the other hand, has a classic "top lever" key from a shotgun.


EL: provisional test, in use since 1852.

13. 9: calibre in mm.

u under star: countermark of a controller, in use between 1877 and 1968.

PV surmounted by a stylized lion: smokeless gunpowder proof, in use from 1898 to 1968.

It is as any probability of a revolver CHAMELOT-DELVIGNE model 1874 manufactured in Liege and which is largely described on the site.

This specimen carries the punches of the proofhouse of Liege, that is to say:

ELG on star in an oval: acceptance, of use of 1846 to 1893.

X under star: countermark of the controller post 1877.

Other markings are:

CHAMELOT-DELVIGNE Inv. Bté: without comment.

21: probably a job number.

J. BECKERS on the amount of stick: it is most probably about a subcontractor.

Arms manufacturers BECKERS Brothers, are announced to ARGENTEAU (Aimed province of Liege) in 1889.

GR. and DJ: also not identified subcontractors.

JIF: is a mark of manufacturer-tradesman deposited by JANSEN Frères street Fusch, 42 in LIEGE.

It should be known that the organization of arms manufacture of Liège was extremely compartmentalized. The manufacturer-tradesman ordered from a subcontractor which made place this order in several workmen in room according to their speciality. The weapon returned then ready to go up in the subcontractor who delivered then to the “manufacturer” who undertook the sale.

These multiples small craftsmen in residence were never indexed.


Many thanks to Roger Papke for the nice pictures.


Also company arms manufacturer of Liège street Fuch 42 and 29 street Duvivier in LIEGE, in fact only one building with the corner of two streets, is registered first once at the Bench of test of Liege of 1927 to 1949 then under denomination JANSSEN Frères S.A. of 1949 to 1954.

Rather wholesaler that manufacture, this company was not announced by the deposit of an unspecified patent.

It held the monopoly of the sale of automatic pistol MELIOR. Sold the weapons of the fabrique Nationale, the weapons and ammunition of PIEPER-BAYARD, ammunition COOPAL and Capsulerie liégeoise inter alias. The company deposited a trademark "J I F" the 27.09.1947.
