7TP -the Polish light tank.

In 1931, 50 new “Vikers-Armstrong Mark E 6-ton” tanks were purchased in Great Britain to renew the arms of the Polish army. An upgraded version of this tank 7TP - 7 tons Polish - has been developed at its base in Poland. A prototype tank, manufactured in 1934, was submitted for testing and research. Their results were positive and the tank was directed to series production. The first 22 tanks from the first series (ordered in March 1935) had two towers. Subsequent production with one tower, armed with a 37 mm anti-tank cannon "Bofors". By September 1939, 132-139 tanks had been produced, which proved their worth in several battles in September and beat more than a dozen Germans Kpfw I and II. A medium-complexity model, in which the biggest problems are multiple complex chassis. It will "eat" about 2/3 of the time, required to assemble this model.
