Vickers-Carden-Loyd light amphibious tank

The Vickers-Carden-Loyd light amphibious tank was a small British experimental tank of the years before the Second World War, a design that resembled a tankette and that the War Office designated the A4E11 and the A4E12. Neither version was taken into British service, but the vehicles were sold abroad, and the buyers included China, Thailand, the Dutch East Indies and the Soviet Union. The Soviet Union went furthest, producing some 1,200 of its own T-37A tanks developed from the British design, and one tank was sold to Japan under a licence. Poland also showed interest in Vickers-Carden-Loyd amphibious tanks in the 1930s, but the negotiations failed and its PZInż works began the PZInż 130 project, an indigenous design inspired by the British concept. The only surviving tank is in the Kubinka Tank Museum in Russia.
