An in-depth study of the Vickers MG in use around the world throughout the 20th Century.
Most Vickers MGs are not clearly marked as to who the manufacturer was as the War Office contract guns did not require anything further than a serial number. The exception to this rule is the Commercial Guns as the manufacturer wished all to know who produced the gun as an additional marketing technique.
Despite this, many components and parts of guns were marked with initials or, in the Second World War, a manufacturers code. In some instances, dates were alse stamped.
