The barrel had the unique feature of being able to swing 180° so the barrel lay flat over the trails for transport and the outer part of the trails could be also folded inward to reduce its size. The gun had a small shield and wooden-spoked wheels. Although rather elderly-looking, its performance was superior to most contemporary designs and the gun was armed with both AP rounds and HE rounds for infantry support.
