Siege Steam Tank Mk. IV (front)

The Siege Steam Tank is a seldom-seen vehicle on the Steam War battlefield. Mainly deployed when enemy fortifications are expected or when artillery will be needed. A heavy cannon is mounted above the driver's compartment with
the commander's hatch behind it. Powered by twin boilers, each powering sperate pistons to turn the huge front wheels. Interior fits four cramped minifigures: driver, stoker, gunner, and commander. (pistons pump as wheel turns)
