Sword bayonet for the 8 mm. Mannlicher-Berthier M1890 Carabine de Cavalerie (cavalry carbine); and, M1892 and M1916 Mousqueton de Artillerie (artillery carbine).
This example was made prior to the turn of the Century by the French State factory, Manufacture Nationale d'Armes de Châtellerault.
This example has the first type crosspiece, with the narrow 15 mm. muzzle-ring (same width as the crosspiece) and hooked lower quillion. This example also has black vulcanized rubber grips.
The earliest examples had maker markings on the blade spine, similar to the M1866 and M1874. Marked blades are scarce, so this practice must have been ceased shortly after production commenced.
Wooden grips were introduced ca. 1905. The second type crosspiece was introduced in 1912, with a wider muzzle ring (that extends over the grip). The third type crosspiece was introduced in during the First World War, with an abbreviated lower quillion.
