Hauler produces photo-etched and resin upgrade sets for armored fighting vehicles (AFVs), airplanes, cars, railway vehicles, and dioramas. They also produce a few resin kits. Their products are in most of the common scale sizes, 1/72, 1/48, and 1/35, but they also produce a number of other items in common railroad hobbyist scales.
The kit for this review is a set of sharply cast resin Dragon Teeth. Dragon Teeth are those square concrete pyramids, most often associated with the Siegfried Line in Germany during World War II. However, these types of fortifications were used in many countries, other than Germany in World War II, and continued to be used today around the world. The idea behind these formations was to create an obstacle to slow the advance of enemy AFVs, or to channel those vehicles into prepared kill zones where anti-tank units waited in ambush.
