TK (TK-3) TKS: Polish tankette
The TK (TK-3) and TKS were Polish tankettes developed during the 1930s and used in the Second World War.
The TK (also known as the TK-3) tankette was a Polish design produced from 1931 based on the chassis of the British Carden Loyd tankette, with an improved hull and more powerful engine, and armour up to 8 mm (0.31 in) thick (10 mm or 0.39 in on the TKS). In 1939, up-arming of the tankettes with Nkm wz.38 FK 20 mm (0.79 in) machine guns began, but only 24 of these were completed before the outbreak of World War II.
On 6 November 1934 Estonia purchased 6 vehicles from Poland, with the contract deal worth over 180,000 krones. The deal also included one additional tracked-lorry, and a motorcycle was given free as a bonus. After the Soviet Union occupied Estonia, these vehicles were put into service with the Red Army.
