Trumpeter continues to produce a wide range of interesting and wide ranging Russian subjects. While the box says that this is the Russian AT-S Tractor, in fact, this is a two-in-one kit. Also included with the prime mover is the Soviet ML-20 152 mm howitzer Mod 1937. As with most Trumpeter kits, the box is sturdy and the sprues are individually packaged and the more fragile parts are wrapped in foam. For the prime mover there are twelve sprues, including four for the individual track links, one sprue of transparent parts and a small PE fret. There are markings for three vehicles, Russian, Finnish, and the German Democratic Republic. For this build, I chose the Finnish markings. For the artillery piece, there are nine sprues, two PE frets, a set of rubber tires and a metal gun barrel. As with most recent Trumpeter models, the parts are well molded in grey plastic, though there is some fine flash and mold lines present on the parts which take some time to clean up.
