The TKS was an improved version of the TK-3 which was Polish re-design of the Carden Lloyd tankette chassis. Production started in 1933 and by 1939, 274 had been built. The TKS was armed with a Hotchkiss 7.92mm wz 25 MG. Later 24 TKS were converted to house a 20mm wz.38 FK-A cannon. This particular kit depicts an experimental design of a light reconnaissance tankette armed with the 20mm FK-A wz.38 cannon. Only one TKW prototype was ever built.
