Model 1906 pistol, cal. 6,35, made by Belgian FN in 1919-20. 

In 1905, Fabrique National d’Armes de Guerre in Herstal, Belgium (best known as FNH), answering to the European demand of a real vest pocket pistol, began to produce a John Moses Browning’s first .25 design, firing the 6.35mm x 15SR cartridge that Browning had developed for the FN gun. J.M. Browning designed a smaller version of his Model 1903, removing the manual safety and the hammer and adding a striker firing pin to ignite the cartridge.

At the beginning FN called this model "FN 1905" or FNVP (“Vest Pocket”) but, as the production really started in 1906, going on sale in July 1906, the FN modified the name in Model 1906.  

Our pistol is the 1906 third variant, known as “Triple Safety Model” with a larger manual safety lever, new slide detents type and with a safety for the magazine.

The gun is a collectible single action model, manufactured in 1919/1920, still now in good condition, with a polished blue finish, checkered horn grips with the FN logo in an oval at the top (In good condition the left grip, while the right has some slight chipping).

The barrel is in good condition with the Liege proof house marks.  

The caliber is 6.35mm (.25ACP) and all its parts are matching numbers.
