The Vickers–Berthier (VB) is a
History
Berthier machine gun
The Vickers–Berthier was based on a
Vickers–Berthier machine gun
In 1925 Vickers in Britain purchased the licence rights of the Berthier Model 1922[1] for production in their Crayford factory, and as a replacement for the Lewis gun. It was an alternative to the water-cooled Vickers machine gun made by the same company.[5] The weapon used a gas and tipping bolt mechanism similar to the Bren light machine gun, was air-cooled like the Bren and also like the Bren had a removable barrel. It was adopted by the Indian Army in 1933.[6] During the British Army trials of several light machine guns which began in 1932, the Vickers–Berthier was in direct competition with the ZB vz. 26. The British Army adopted the latter, modified and known as the Bren light machine gun, and the Vickers–Berthier was adopted by the British Indian Army.[7] A production line for the Vickers–Berthier Light Machine-Gun Mk 3 was established at the Rifle Factory Ishapore.[8]
Appearance and design
The Vickers–Berthier Light Machine Gun has a 30-round box magazine and a bipod stand, and is sometimes mistaken for the Bren as both used a similar curved magazine to accommodate the rimmed .303 British cartridge.[8]
It was slightly heavier, at 24 pounds (11 kg), than the Bren's 22 lb (10.0 kg). It was also slightly longer, and harder to stow away. The Vickers–Berthier also had a slower cyclic rate of 500 rpm.[9] The only major advantage the weapon had over the Bren was the far simpler design; it could be produced more efficiently.[7]
It existed in five versions : Mk I, Mk II, Mk II light, Mk III and Mk IIIB.[10] Mark 1 was introduced in 1928, Mark 2 in 1931 and Mark 3 in 1933.[11]
Use
Apart from India, it was sold only to Latvia and Bolivia,[12] but the design was modified into the Vickers K machine gun, for aircraft use called the Vickers Gas Operated (VGO).[8]
In Indian service, it was replaced from 1942 by Brens[13] but continued to serve with reserve units of the Indian Army into the 1980s.[1]
