Russian infantry light tank T-18
Eastern Express 35003

The T-18 light tank (also called MS-1, Russian: Maliy Soprovozhdeniya-Perviy, "First Small [Vehicle for] Support") was the first Soviet-designed tank. Produced from 1928–31, it was based on the Renault FT-17, with the addition of a vertically sprung suspension.
 
The T-18 and its derivatives were essentially unsuccessful designs, but they gave Soviet industry its first experiences in designing armoured vehicles, and in the meantime a number of foreign tank designs were available for production. [Wikipedia]
