StuH 42 28mm 1/56 Scale by Blitzkrieg Miniatures. In 1942, a variant of the StuG III Ausf. F was designed with a 105 mm (4.1 in) howitzer instead of the 7.5 cm StuK 40 L/43 cannon. These new vehicles, designated StuH 42 (Sturmhaubitze 42, Sd.Kfz 142/2), were designed to provide infantry support. The StuH 42 mounted a variant of the 10.5 cm leFH 18howitzer, modified to be electrically fired and fitted with a muzzle brake. This is a resin model with very little assembly required. Tank commander figure not included. Suitable for Bolt Action and other WWII rule systems.
