The 75mm PaK-40 was a standard anti-tank gun of the Wehrmacht during
WWII. Many were captured by the Red Army during the war.
In 1955, the USSR transferred a small number of PaK-40 guns to North
Vietnam. They had been captured during WWII and kept is storage for ten
years afterwards. They were refurbished before the transfer.
