The Netherlands accepted the 11 mm black powder Beaumont single shot infantry rifle in 1881. In 1888 the rifle was converted to a repeating rifle by adding the 4 round Vitali magazin. 
In 1888 also the first model bayonet was improved by replacing the single screw locking ring by two tightening screws.
The Beaumont M 1871/88 was already replaced in 1895 by the 6.5 mm Mannlicher rifle.

Some authors describe the one screw tightening ring as the second model and the the two screw model as the first model, which is an error.
