It is a completely new subject in the 1/72 scale Dragon Armor Pro series. It features brand new tooling that has been leveraged to the best possible levels of accuracy and easy assembly. The upper hull, lower hull and turret, for example, are all produced as one-piece components via slide-mold technology. The whole plastic kit is a perfect blend of detail and convenience. This is exemplified by the one-piece DS tracks, which are even detachable just as they were on the original assault gun. Although the novel BT-42 was a desperate Finnish design used in combat during WWII, this kit marks the exciting start of its new modeling career.
