HOTCHKISS H35

Its conception is close to the Renault R35, the H35 is equipped with the same APX-R turret. The H35 is equipped with the 37mm SA18 L/21 gun and sometimes with a 37mm SA38 L/33 gun. Some were fitted with AMX crossing tails. About 400 Hotchkiss H-35 have been produced. An easy tip to distinguish between R35 and H35/39 tanks : the Hotchkiss tanks have 6 wheels mounted in pairs on bogies while the R35 tanks have only 5 wheels (the 1st mounted independently, the other 4 on 2 articulated bogies).
