Production information
The Mk. VI, Mk. VI*, and Mk. VII Vickers MGs were the secondary armament for all Tanks in British Service until the gradual introduction of the Besa and Browning MGs in the early 1940s. This meant that they were being produced in line with the developments and demands of the Tank ‘fleet’. As well as being produced from scratch, they were also being converted from Mk. I guns, either from guns that needed repair anyway or from new production stock. The majority of components were common to all guns in .303-inch.
The following table sets out the production data for the Mk. VI, Mk. VI*, and Mk. VII Vickers. It is unclear from the information available whether references to Mk. VI also include Mk. VI* guns. Furthermore, the proportion split when covering multiple marks is unknown.
