Users

Foreign buyers included China (29 or 32 tanks),^[2] Thailand, the Dutch East Indies (two delivered in 1937)^[3] and the USSR, with the latter producing some 1200 of the T-37A tanks developed from the A4E11/12. One tank with a licence was sold to Japan.^[4] Poland was interested in Vickers-Carden-Loyd amphibious tanks in the 1930s, but negotiations failed and instead the PZInż works started the PZInż 130 project, an indigenous design inspired by the British concept.
