The ejector rod is mounted on the upper right side of the frame, the barrel is equipped with a pinched blade front sight and a notch in the hammer serves as the rear sight. The revolver has the nine shot pinfire cylinder, the selector is mounted in the center on the hammer and fires the lower percussion barrel when in the down position. The left rear barrel flat is marked "COL LA LEMAT BRTE 131" with no other visible markings present. The final LeMats were produced in 36 and 44 caliber, original LeMats were chambered for 42 caliber, which was very common for contemporary revolvers at the time, and this revolver may have been produced to satisfy a need for both calibers in one revolver. Pinfire ammunition was invented in 1832 by Parisian gun maker Casimir Lefaucheux.
It’s a pocket pistol designed for personal defense and chambered in 7mm Pinfire. This is certainly unique to the traditional 16 or 28 gauge smooth bore normally found on these revolvers. WTW: Lefaucheux’s 7mm Pinfire Revolver Mike the Mook We recently came across an interesting revolver with a folding trigger that extends itself when the hammer is cocked. This particular revolver has a 6 1/2" upper octagon 36 caliber pinfire barrel and the lower 4 5/8" round barrel is rifled and gauges at 44 caliber percussion.
Traditionally known as the "Grapeshot", this is 1 of approximately 1,000 Belgian Brevete revolvers produced of which only a handful are pinfire.
