Jules Jacquemart, Liege, Belgium.

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.
