Egypt’s provision of Vickers Guns was from the British War Office. Asides from the provision of standard British service Mk. I guns, a special production run was actually ordered by the War Officer for 200 Mk. I .303-inch guns with the serial number prefix of ‘ET’. These were supplied during WW2.
Many of these ‘ET’ guns were captured during the ‘Six-Day War’, of 1966, by the Israelis. They were then converted to 7.92mm and presumably used in defensive positions.
A number of Egyption-used Vickers guns were released on the collectors market in 1986.
