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

Jacquemart Ateliers Herstal

Here is a shotgun juxtaposed with external hammers, back plates, key of opening between the hammers, of manufacture of Liège and charged with American history.

The barrels seem very short and look more like a "coach gun" to me.

Markings :

Peron: inspection since 1853;

crowned ELG: acceptance since 1893

12-65 in omega lying: nominal gauge and length of the casing, since 1924

Y under star: countermark of a controller, since 1877

EL: provisional test, since 1852

18. 3: gauge in mm

Choke 16. 2: choke barrel

D crowned: more than likely the gunner Delcour

HJA: it could be the Workshops Jacquemart in Herstal, but it is not sure at all because they were active between 1943 and 1952 then under another denomination until 1966. However, as we will see later, this does not fit the story of the Miller Brothers 101 Ranch and its great show in which Buffalo Bill participated.

But first, let's locate Ponca City, in northern Oklahoma:,_Oklahoma

The history of this city is intimately linked to the Miller Brothers and their huge ranch and also their 101 Ranch Wild West Show very active between 1907 and 1927:

In any case, this rifle, which has suffered the outrages of time, must date from this period and even more precisely from the end since it is after 1924. Unless it belonged to a member of the show who "embellished" his rifle as a souvenir.

What is in any case very surprising is the absence of an annals date (at least as seen from here.....): now, we know that the Belgian proofhouse introduced the annals letters in 1922.

The Monobloc.

Jacquemart began the production of this pistol before the First World War; so that it appears, it died little after and the production was continued by the widow and ceased in 1914; since this time one did not intend any more to speak about the company; although Pollard quoted the gun in its book of 1920, nothing proves that it spoke about a model after war.

The weapon of Jacquemart was an automatic of 6,35 mm to not fixed cylinder head, of original design. The carcass and the box of cylinder head formed a single part with the gun, and the external surface of the box of cylinder head presented grooves similar to the contemporary models of Pieper. At the interior of the box of cylinder head was the mobile cylinder head whose grooved wings covered by slits practised in the sides of the box of cylinder head, in order to be able to seize the cylinder head and to draw it behind for the loading. The higher part of the cylinder head formed a protuberant pipe which contained the spring recuperator and which penetrated in a tubular housing placed in the higher part of the carcass, above the gun. A stem-guide passed through this part of the cylinder head and was screwed in the frontal part of the carcass; when the cylinder head moved back, the tubular part compressed the spring recuperator around the fixed stem. The charger placed 6 blows and the gun had a length of 2 inches. The box of cylinder head was marked "the Automatic Monobloc Patented Gun", and the handles carried monogram "JJ" to the flowered style.

This automatic pistol of gauge 6,35 mm is a realization of Joseph JACQUEMART.

The carcass, the barrel and the slide are of only one part what justifies “Monobloc” name.
