A year later, this 16.5mm-caliber short rifle was followed by a big brother, the 20.5 mm Fusile de Rempart modele 1838.
Another follow-on Fusile de Rempart modele 1842 soon emerged, again looking much like its predecessor, though the ramrod head was remodeled, a spur on the rear of the trigger-guard eliminated and the barrel fitted with a bar for a wavy-bladed yataghan-style bayonet.
The Berthier setup was just too good to be restricted to carbines, and soon after its introduction, a rifle version, the fusile
de tirailleur Indochinois Modele 1902, for use by troops in Indochina, made its appearance.
The resulting new rifle was officially called the Fusile
Modele 1866, but unofficially named the Chassepot, after its inventor, Antoine Alphonse Chassepot.
The primary French muskets of the period, the .69-caliber Fusile
Modele 1822 T Bis (a percussion conversion from an older flintlock musket) and the Models 1842 and 1853-57, not to mention shorter rifles and carbines built on similar platforms, with their high, straight hammers, seemed to lend themselves to a side-swinging conversion, a la the Snider.
